7/3u = 21
Multiply both sides by 3
7u = 63
Divide both sides by 7
u = 9
Answer:
no solution
Step-by-step explanation:
Simplifying
11q + -6 = 3q + 8q
Reorder the terms:
-6 + 11q = 3q + 8q
Combine like terms: 3q + 8q = 11q
-6 + 11q = 11q
Add '-11q' to each side of the equation.
-6 + 11q + -11q = 11q + -11q
Combine like terms: 11q + -11q = 0
-6 + 0 = 11q + -11q
-6 = 11q + -11q
Combine like terms: 11q + -11q = 0
-6 = 0
Solving
-6 = 0
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.
You find volume by multiplying length times width so the answer would be 300
Answer:
12a - 6b
Step-by-step explanation:
Given
8a + 3b + 4a - 9b ← collect like terms
= (8a + 4b) + (3b - 9b)
= 12a + (- 6b)
= 12a - 6b
