Brainiest and you will get 10 points! what is the value of p in the equation 4p + 3(p + 4) = 12p + 12? 12, 1, 0, -1. which of these is a simplified form of the equation 7x + 4 = 5 + 3x + 1x? 3x = 9, 3x = 1 , 11x = 9, 11x = 1 what is the value of z in the equation 3z + 5 = 4z − 8? 13, 1, -13, -1 the work of a student trying to solve the equation 3(4x − 2) = 9 + 2x + 5 is shown below: step 1: 3(4x − 2) = 9 + 2x + 5 step 2: 12x − 2 = 14 + 2x step 3: 12x − 2x = 14 + 2 step 4: 10x = 16 step 5: x = 1.6 in which step did the student first make an error and what is the correct step? step 2: 12x − 2 = 4 + 2x step 2: 12x − 6 = 14 + 2x step 3: 12x + 2x = 14 + 2 step 3: 12x − 2x = 14 − 2

30 points for full answer. 1. solve the equation: (x-4)^2-28=8 show your work. don’t forget that you will get two answers. use the square root property to solve 2. this is josh’s solution for the equation : step 1: x² - 6x – 7 = 0 step 2: x² - 6x = 7 step 3: x² - 6x + 9 = 7 + 9 step 4: (x – 3)² = 16 step 5: x – 3 = 16 step 6: x = 19 step 7: x – 3 = -16 step 8: x = -13 where did josh make his mistake? what are the solutions to this equation? show all of your work. this problem is solved using completing the square. the mistake was in step here is how to correctly solve the equation:

Can someone me, this is my last question i have been stuck on it for 30 min the work of a student to solve a set of equations is shown: equation a: y = 15 − 2z equation b: 2y = 3 − 4z step 1: −2(y) = −2(15 − 2z) [equation a is multiplied by −2.] 2y = 3 − 4z [equation b] step 2: −2y = 15 − 2z [equation a in step 1 is simplified.] 2y = 3 − 4z [equation b] step 3: 0 = 18 − 6z [equations in step 2 are added.] step 4: 6z = 18 step 5: z = 3 in which step did the student first make an error? step1 step 2 step 3 step 4

Consider the sequence of steps to solve the equation: 2(x − 4) + 6x = 9x − 10 given ⇒ 2(x − 4) + 6x = 9x − 10 step 1 ⇒ 2x − 8 + 6x = 9x − 10 step 2 ⇒ 2x + 6x − 8 = 9x − 10 step 3 ⇒ 8x − 8 = 9x − 10 step 4 ⇒ 8x − 8x − 8 = 9x − 8x − 10 step 5 ⇒ 0 − 8 = x − 10 step 6 ⇒ −8 = x − 10 step 7 ⇒ −8 + 10 = x − 10 + 10 step 8 ⇒ 2 = x + 0 step 9 ⇒ 2 = x which step in solving this equation is justified by the commutative property of addition? a) step 1 ⇒ 2x − 8 + 6x = 9x − 10 b) step 2 ⇒ 2x + 6x − 8 = 9x − 10 c) step 3 ⇒ 8x − 8 = 9x − 10 d) step 4 ⇒ 8x − 8x − 8 = 9x − 8x − 10
