Solving Equations
equation
Uses an equal sign to show that two expressions are equal
Distribute 4
What is the final step to solve 4(3x + 2) = 28 ?
Distribute 11
What is the first step to solve 11(5 + 4x) = 55 ?
Subtract 4 to both sides
What is the first step to solve 4 + 5x = 19 ?
Distribute 4
What is the first step to solve 4(3x + 2) = 28 ?
Add 3 to both sides.
What is the first step to solve 8 = n/7 - 3 ?
Add 11 to both sides.
What is the first step to solve 8x - 11 = 34 ?
Distribute 9
What is the first step to solve 9(5x - 4) = 81 ?
Add 7 to both sides.
What is the first step to solve x/4 - 7 = 12 ?
Divide by 5 to both sides.
What is the second step to solve 4 + 5x = 19 ?
Multipy by 7 to both sides.
What is the second step to solve 8 = n/7 - 3 ?
Divide by 8 to both sides.
What is the second step to solve 8x - 11 = 34 ?
Multiply by 4 to both sides.
What is the second step to solve x/4 - 7 = 12 ?
