Substitute and Solution

What is the solution to this equation?

• one solution

• no solution

• infinite solutions

• none of these

Solve:
3x + 15 = 3(x + 5)

• No Solution

• x = 15

• Infinitely Many Solutions

What is the solution to the equations?

• one solution

• no solution

• infinite solutions

• none of these

x = y - 2
4x + y = 2

• (2,0)

• (0,2)

• (0, -2)

• (-2,0)

Which choice shows substitution correctly?

• 3x - (-6x +3) = 10

• 3(-6x + 3) - y = 10

Solve for x and y (Use Substitution)

y = 2x + 1

y = 4x - 1

• (1,3)

• (-1,-3)

• (-1,3)

• (3,1)

• (1,1)

Solve the following systems of equations using substitution:

x = 6

y = 2x - 3

• (6, 6)

• (6, 9)

• (9, 6)

• (9, 9)

Solve using Substitution Method

y = -6

-3x - 6y = 24

• (6, 6)

• (6, -6)

• (4, -6)

• (-6, 4)

Solve the system by substitution method

x = 3

2x + 5y = 16

• (3,2)

• (3, 0)

• (2, 5)

• (2,10)

If x = -3, in the equation -2x + y = 15, what is y? Type in the number.
