Question

Solve the equation -
`(w)/(5)` +9=13. What is w?

Answer 1

w = -20

Explanation:

-
`(w)/(5)` + 9 = 13

Shift the (+9) to the other side of the equation. (+9) will turn into (-9).

-
`(w)/(5)` = 13 - 9

= 4

Shift the (÷5) to the other side of the equation. (÷5) will turn into (×5).

-w = 4 × 5

= 20

Multiply both sides of the equation by (-1) so that -w will turn into w.

w = (-1) × 20

w = -20
