Question

Six is equal to three times the sum of a number and seven

Answer 1

1. Write as an equation

6=3(x+7)

2. Solve the equation by first distributing

6= 3x +21

3. Subtract 21 from both sides of the equation

6-21=3x

4. Combine like terms

-15=3x

5. Divide by three to isolate the variable

-15/3 =x

6. Simplify

-5=x
