MULTIPLE CHOICE QUESTION
1 min • 1 pt
Complete the first step ONLY of the following problem
y=2x-3
2x-5y=-8
2(2x-3)-5y= -8
2x-5y(2x-3)= -8
2x-5(2x-3)= -8
2(y=2x-3)-5y = -8

MULTIPLE CHOICE QUESTION
1 min • 1 pt
Complete the first step only
7y - 8x = 10
y= 4x-3
7(4x-3) - 8x = 10
7y(4x-3)-8x = 10
7y - 8(4x-3)=10
7y-8x(4x-3) = 10

MULTIPLE CHOICE QUESTION
1 min • 1 pt
Complete the first step ONLY of the following problem
2x-3y=-1
x= -3x +2
-3(2x-3y) +2 = -1
2(-3x+2)-3y = -1
2x(-3x+2)-3y = -1
2x-3(-3x+2)= -1

Complete first step ONLY
x= 8y -3
x + y= 7
8y - 3 = 7
x + 8y - 3 = 7
x(8y - 3) + y = 7
8y - 3 + y = 7
