An equation is shown.
5x + 3=4
-2

The answer is -1
-5/2x - 3/2 = 4
cross multiply -5 x 2
cross multiply -3 x 2
-10x - 6 = 4
add 6 to both sides
-10x = 10
divide -10 on both sides to get x alone
x = -1

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
