Solve for Variable on Both Sides Equal Sign

In the equation 5d - 1= 2d - 7, we need to get the variable to one side of the equal sign. What would we do to move the variable to the left side?

• -2 from both sides of the equal sign

• -5d from both sides of the equal sign

• -2d from both sides of the equal sign

• + 7 on both sides of the equal sign

In the equation 5d - 1= 2d - 7, after we -2d from both sides, we get 3d - 1 = -7. What does d = if you finish solving it?

• d = -1

• d = 1

• d = 2

• d = -2

In the equation 4c + 8 = 14, c is the ______________.

• constant

• coefficient

• calculation

• varialbe

Solve the equation 5(b - 2) = -10

• b = 4

• infinite solutions

• no solution

• b = 0

Which equation below would give you an answer of infinite solutions (all real numbers)?

• 4x + 10 = 0

• 4x + 10 = 4x

• 4x + 10 = 4x + 8

• 4x + 10 = 4x + 10

12x = 144

• x = 12

• x = 4

• x = 2

• x = 132

y + 8 = 20

• 10

• 11

• 12

• 13

17 = x + 3

• x = 20

• x = 14

• x = 13

• x = 19

x + 12 = 20

• x = 32

• x = -32

• x = 8

• x = -8

4 + b = 30

• -34

• 34

• -26

• 26
