Step-by-step explanation:
b - 4 = 3
Add 4 to each side
b - 4+4 = 3+4
b = 7
-32 = 8w
Divide by 8
-32/8 = 8w/8
-4 = w
n/7 = -4
Multiply by 7 to each side
n/7 *7 = -4*7
n = -28
Answer:
1. b = 7
2. w = -4
3. n = -28
Step-by-step explanation:
1. b - 4 = 3
Tip: Whenever there’s a number being subtracted or added, it’s best to make that number a 0
Step 1. Add 4 to both sides
b - 4 = 3
b + 4 = +4
b = 7
—————————————
2. -32 = 8w
Step 1. Isolate the variable
(by dividing both sides by 8)
w = -32/8
w = -4
—————————————
3. n/7 = -4
Step 1. Multiply 7 x -4
n = -28
