Sagot :
[tex]8=8v-4(v+8) \\\\ 8=8v-4v-32 \\\\ 8=4v-32 \\\\ 8+32=4v \\\\ 40=4v \\\\ \boxed{v=\frac{40}{4}=10} [/tex]
8 = 8v - 4 (v + 8) :First, distribute the -4 to whatever is inside the parenthesis
8 = 8v - 4v - 32 :Now, combine like terms
8 = 8 - 32 :Then, add the 32 over to the 8
+32 +32
(40 = 4v) ÷ 4 :Then, divide the entire equation by 4
10 = v
Your final answer is:
v = 10
8 = 8v - 4v - 32 :Now, combine like terms
8 = 8 - 32 :Then, add the 32 over to the 8
+32 +32
(40 = 4v) ÷ 4 :Then, divide the entire equation by 4
10 = v
Your final answer is:
v = 10
