Step-by-step explanation:

6 - 3x + 15 = 5x - 11
Simplify 6 - 3x + 15 to -3x + 21
-3x + 21 = 5x - 11
Add 3x to both sides
21 = 5x - 11 + 3x
Simplify 5x - 11 + 3x to 8x - 11
21 = 8x - 11
Add 11 to both sides
21 + 11 = 8x
Simplify 21 + 11 to 32
32 = 8x
Divide both sides by 8
32/8 = x
Simplify 32/8 to 4
4 = x
Switch sides
<u>x = 4</u>

Answer:
b = a + 3.75
Step-by-step explanation:
a = 4b - 15
You are solving for b. Isolate the b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, add 15 to both sides
a (+15) = 4b - 15 (+15)
a + 15 = 4b
Next, divide 4 from both sides. Remember to divide from all terms.
(4a + 15)/4 = (4b)/4
b = (4a)/4 + (15)/4
b = a + 15/4
b = a + 3.75 is your answer
