Question

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

Answer 1

problem one: w = 10 or B

Problem two: x = 96 or A

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
