Question

Bertha adds 5 to a number, then multiplies the sum by negative 2. The result is 6. Write and solve an equation to find the number, x.

Answer 1

`- 2(x + 5) = 6 \\ - 2x - 10 = 6 \\ - 2x = 16 \\ x = - 8`

Answer 2

-8

Explanation:

Take the number, x and follow the steps

(x + 5) * -2 = 6

Then solve the equation

(x + 5) = -3 Divide each side by -2

x = -8 Subtract 5 from each side
