15 + 3w = 45

A. w=5

B. w=10

C. w=15

D. w=30

15 = x/6 - 1

A. x=96

B. x=90

C. x=84

D. x=80

problem one: w = 10 or B

Problem two: x = 96 or A

Step-by-step explanation:

Problem One

I take it these are two different questions.

15 + 3w = 45 Subtract 15 from both sides

15 - 15 + 3w = 45 - 15 Combine like terms

3w = 30 Divide by 3

3w/3 = 30/3 Do the division

w = 10

Problem 2

Switch Sides

x/6 - 1 = 15 Add 1 to both sides

x/6 - 1 + 1 = 15 + 1 Combine like terms

x/6 = 16 Multiply both sides by 6

x/6 * 6 = 16 * 6 Combine

x = 96
