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 ?

2 (x + 2) = 2

x = -1

3x = 2 (7 + 5x)

x = -2

12 (-2x - 9) = -12

x = -4

12 (-x + 5) = 144

x = -7

245 = -5 (4x - 17)

x = -8

5 (7x - 13) = -30

x = 1

-210 = -7 (9x - 60)

x = 10

x + 3 = 3 (11 - 3x)

x = 3

2 (3x + 1) = 7x - 5

x = 7
