2(4v-3)=2(5v-3)-2v
Help explain it to me please.

Answers

Answer:

All Real Numbers

Step-by-step explanation:

First, use the distributive property to expand everything:

8v-6=10v-6-2v

Then, combine like terms:

8v-6=8v-6

Then, subtract 8v from both sides to isolate the variable:

0-6=-6

-6=-6

Any real number you substitute with v will make the equation always true, as -6 always is equal to -6. Therefore, the answer is All Real Numbers.

Alll that equals -6 hope this helps
