Question

Solve the equation

a = - 4

Evaluate

7 a = 2 (a - 10)

Expand the expression

More Steps

Evaluate

2 (a - 10)

Apply the distributive property

2 a - 2 \times 10

Multiply the numbers

2 a - 20

7 a = 2 a - 20

Move the variable to the left side

7 a - 2 a = - 20

Subtract the terms

More Steps

Evaluate

7 a - 2 a

Collect like terms by calculating the sum or difference of their coefficients

(7 - 2) a

Subtract the numbers

5 a

5 a = - 20

Divide both sides

\frac{5 a}{5} = \frac{- 20}{5}

Divide the numbers

a = \frac{- 20}{5}

Solution

More Steps

Evaluate

\frac{- 20}{5}

Reduce the numbers

\frac{- 4}{1}

Calculate

- 4

a = - 4
