Set Up Substitution

Which answer shows the correct first step for substitution?

• -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 - 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?

y = -2x + 18

y = 8

• 8 = -2x + 18

• y = -2(8) + 18

• x = -2x + 18

• y = -2x + 18

Which answer shows the correct first step for substitution?

• 8(-2x + 3) + 4y = 12

• 8x + 4y = 12(-2x + 3)

• 8x + 4y = 12

• 8x + 4(-2x + 3) = 12

What is the solution to this system? Solve by substitution.
y= 4x + 3
2x - 3y = 21

• (3,-9)

• (-3,-9)

• (-3,9)

• (0,1)

Which answer shows the correct first step for substitution?

• 5(4) + 3y = 7

• 5x + 3y = 7(4)

• 5x + 3y = 7

• 5x + 3(4) = 7

Which answer shows the correct first step for substitution?

• 2(5x - 27) + 3y = 4

• 2x + 3y = 4(5x - 27)

• 2x + 3(5x - 27) = 4

• 2x + 3y = 4

Which answer shows the correct first step for substitution?

• 12(-3x - 6) + 4y = 3

• 12(-3x - 6)= 3

• 12x + 4(-3x - 6) = 3

Which answer shows the correct first step for substitution?

• 11x - (11x) = 3

• -11x = 3

• 11(11x) - y = 3

Which answer shows the correct first step for substitution?

• 2(-6y) + 12y = 0

• 2x + 12(-6y) = 0

• 2( -6y) = 0
