Simplify: 7p - 4 + 12p
To simplify this expression, simply combine like terms. The expression has two variable terms and one constant term. The variable terms are 7p and 12p, and the constant term is -4. Begin simplifying by combining variable terms (add them together).
7p + 12p
19p
This term (19p) replaces the first p-term in the original expression.
As there is only one constant term (-4), that is all there is to be done to simplify this expression.
Answer:
19p - 4

Simplif 1/2t to t/2
t/2 + 8 = 5/2t - 10
Simplify 5/2t to 5t/2
t/2 + 8 = 5t/2 - 10
Multiply both sides by 2
t + 16 = 5t - 20
Subtract t from both sides
16 = 5t - 20 - t
Simplify 5t - 20 - t to 4t - 20
16 = 4t - 20
Add 20 to both sides
16 + 20 = 4t
Simplify 16 + 20 to 36
36 = 4t
Divide both sides by 4
36/4 = t
Simplify 36/4 to 9
9 = t
Switch sides
<u>t = 9</u>
