</span>step 1: simplify 18x - 72 = 5x - 7
23x = -79
step 2: solve it x = -3.43
Answer:
the aswer is 32
Step-by-step explanation:
Answer:
5xy^2(5 - 3x)
Step-by-step explanation:
The GCF is 5xy^2
so the factors are 5xy^2(-3x + 5) or 5xy^2(5 - 3x)
Simplifying
6k + -9 = -15
Reorder the terms:
-9 + 6k = -15
Solving
-9 + 6k = -15
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + 6k = -15 + 9
Combine like terms: -9 + 9 = 0
0 + 6k = -15 + 9
6k = -15 + 9
Combine like terms: -15 + 9 = -6
6k = -6
Divide each side by '6'.
k = -1
