In this unit, you solved two-step equations. a two-step equation is an equation of the form px + q= r. it takes two steps to solve for the variable x. for example, 3× +(-5)= 19 is a two-step equation. how could you transform this particular equation to create a three step equation? list several ways you could transform it using common math operations. next, try solving one of the three step equations you created for x. (use a guess and check strategy, if necessary.) what additional step is required to find the solution? in your opinion, is solving the three step equation more difficult than solving a two step equation? why are why not? do you think there is limit to the number of steps it takes to solve an equation? explain ( i need the work to be shown for this )

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
