Answer:
b = 5
Step-by-step explanation:
4 ( 3b + 2 ) - 5b = 43 Given
( 4 • 3b + 4 • 2 ) - 5b = 43 Distributive Property
12b + 8 - 5b = 43
12b - 5b + 8 = 43 Combine like terms
7b + 8 = 43
7b + 8 - 8 = 43 - 8 Subtraction Property of Equality
7b = 35
7b / 7 = 35 / 7 Division Property of Equality
b = 5

I believe the answer to that is <
Answer:
x = 1
Step-by-step explanation:
8x - 5(x - 3) = 18
8x - 5x + 15 = 18 <em>[Expand the brackets]</em>
3x = 3 <em>[Separate variables and constants]</em>
<u>x = 1</u>
