Make w the subject of the formula 5 (w + x) = 3x + 9

w = 9 - 2x/5

Step-by-step explanation:

5 (w + x) = 3x + 9 ... open the bracket

5w + 5x = 3x + 9

Combine like terms:

5w + 5x - 3x = 9

5w + 2x = 9

Make w the subject of the equation

5w = 9 - 2x

Divide both sides by 5

w = 9 - 2x/5

w = 3x+9/5 - x

Step-by-step explanation:

5 (w + x) = 3x + 9

Divide both sides by 5 to eliminate 5 on the left side

5 (w + x) / 5 = 3x + 9/5

w + x = 3x + 9 / 5

Subtract x from both sides to isolate w

w + x - x = 3x+9 / 5 - x

w = 3x+9/5 - x
