Equation on Both Sides of the Equal Sign

What is the correct step to solve for the variable?

• add 25 to both sides

• subtract 25 to both sides

• divide 25 on both sides

• multiply 25 on both sides

The first step to solving the equation g - 3 = -12 is to . . .

• divide by -3 on both sides of the equal sign

• multiply by -3 on both sides of the equal sign

• subtract 3 on both sides of the equal sign

• add 3 on both sides of the equal sign

From the last equation g - 3 = -12, after you add 3 on both sides of the equal sign, what is your answer?

• g = -15

• g = -9

• g = 36

• g = 15

What is the first step in solving for w in the equation 3w + 5 = 14?

• Add 5 to both sides of the equal sign

• Divide by 3 on both sides of the equal sign

• Subtract 5 from both sides of the equal sign

• Multiply by 3 on both sides of the equal sign

Solve the equation 4n - 7 = -23

• n = -4

• n = 4

• n = 7.5

• n = -7.5

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

• b = 4

• infinite solutions

• no solution

• b = 0

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

Solve.

• 12

• 13

• 14

• 15

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

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
