Which answer shows the correct first step for substitution?

y = -6x + 5

-2x + y = 5

• -2(-6x+5)+y=5

• y = -2x + 5

• -2x + (-6x + 5) = 5

• -2x + y = 5( -6x + 5)

Which answer shows the correct first step for substitution?

x = -3y - 8

x - 2y = -3

• x - 2(-3y - 8) = -3

• x - 2y = -3(-3y - 8)

• (-3y - 8) - 2y = -3

• x - 2y = -3

Which answer shows the correct first step for substitution?

8x + 4y = 12

y = -2x + 3

• 8(-2x + 3) + 4y = 12

• 8x + 4y = 12(-2x + 3)

• 8x + 4y = 12

• 8x + 4(-2x + 3) = 12
