Answer:
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
