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

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

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

Solve the following systems of equations using substitution:

y = 8

y = -4x + 4

• (8, -1)

• (-28, 8)

• (-1, 8)

• (8, -28)
