Simplify by removing parentheses Simplify 5(4 + y): Distribute the 5 to each term in (4+y) 5 * 4 = (5 * 4) = 20 5 * y = (5 * 1)y = 5y Our Total expanded term is 20 + 5y
Our new term is 72 + y = 20 + 5y
Simplify by removing parentheses Our new term is 72 + y = 20 + 5y
Group variables
Group our variables y and 5y subtract 5y from both sides y + 72 - 5y = 5y + 20 - 5y
Cancel 5y on the right side:
-4y + 72 = 20
Group constants
Group our constants 72 and 20. subtract 72 from both sides -4y + 72 - 72 = 20 - 72
Cancel 72 on the left side:
-4y = -52
Divide each side of the equation by -4
-4y
-4
=
-52
-4
y = 13
y = 13
What is the Answer?
y = 13
