the table shows the solution to the equation |2x − 3| − 1 = 2:

step 1 |2x − 3| = 2 + 1
step 2 |2x − 3| = 3
step 3 2x − 3 = 3 or 2x + 3 = 3
step 4 2x = 6 or 2x = 0
step 5 x = 3 or x = 0
which is the first incorrect step? (1 point)

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
