Substitute Value Into Equation

You are given the equation
2x + 3y = 6
Substitute the values (3, 0) into the equation. Which equation below shows a correct substitution?

• 2(0) + 3(3) = 6

• 2(3) + 3(0) = 6

• 3x + 0y = 6

• 2(3x) + 3(0y) = 6

Which choice shows substitution correctly?

• 3x - (-6x +3) = 10

• 3(-6x + 3) - y = 10

Which number from the data set can be substituted to make the following equation true :

7x + 2 = 100/x + 5

• 4

• 7

• 8

• 11

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