Question

Solve:
7w+5=3w -15 please help

Answer 1

w =-5

Explanation:

Group the variables and constant on each side

remember that the signs will change while switching the places.

7w-3w=-15-5

4w=-20

divide the coefficient to keep only the variable and find its value

4÷4w= -20÷4

w= -5

therefore w is -5

Answer 2

w=−5

Explanation:

Step 1: Subtract 3w from both sides.

7w+5−3w=3w−15−3w

4w+5=−15

Step 2: Subtract 5 from both sides.

4w+5−5=−15−5

4w=−20

Step 3: Divide both sides by 4.

4w4=−204

Answer: w=−5

Hope this helps.
