The steps to solve 3 (x + 3) = 30 are:

• divided by 3 then subtract 3 on both side

• subtract 3 then divided by 3 on both side

• multiply by 3 then subtract 3 on both side

• subtract 3 then multiply by 3 on both side

The first step in solving this equation is

3x - (8 - x) = 47 - x

• Distribute -1

• Distribute 3x

• combine like terms

• inverse operations

The second step in solving this equation is

3x - (8 - x) = 47 - x

• Distribute -1

• Distribute 3x

• combine like terms

• inverse operations

After I combine like terms from step 2 I will

3x - (8 - x) = 47 - x

• Distribute -1

• Move the x's to one side

• combine like terms

• inverse operations

After I get my x's on one side I'll move

3x - (8 - x) = 47 - x

• Distribute -1

• the x's to one side

• my seat

• the constants to the other side using inverse operations.

Four more than twice a number is 8.

• 8n + 4 = 2

• 4n + 2 = 8

• 2n + 8 = 4

• 2n + 4 = 8

Three more than four times a number is 15.

• 4x + 3 = 15

• 3x + 4 = 15

• 4x + 15 = 3

• 15x + 3 = 4

Six less than six times a number is 12.

• 6m - 6 = 12

• 6m - 12 = 6

• 12m - 6 = 2

• 12m - 6 = 6

The difference between 5 times a number and 3 is 12.

• 3h - 5 = 12

• 5h - 12 = 3

• 5h - 3 = 12

• 12h - 3 = 3
