Question

#11 i
Solve 7w-9=13 - 4w.
W =

Answer 1

w=2

Explanation:

Step 1: Simplify both sides of the equation.

7w−9=13−4w

7w+−9=13+−4w

7w−9=−4w+13

Step 2: Add 4w to both sides.

7w−9+4w=−4w+13+4w

11w−9=13

Step 3: Add 9 to both sides.

11w−9+9=13+9

11w=22

Step 4: Divide both sides by 11.

11w/11=22/11

w=2
