Question

Can someone solve -3 = x + 7 - 4?

and 8v - 3 + 3v = 8

and -v + 3v = 4

step by step?

Answer 1

-3=x+7-4

-3-7+4=x

x=-6

8v-3+3v=8

8v+3v=8+3

11v=11

V=1

-v+3v=4

2v=4

V=2

Explanation:

Answer 2

x= -6

v= 1

v= 2

Explanation:

-3= x+7-4, combine like terms by subtracting seven from four

-3= x+3, subtract three from both sides

-6= x

8v-3+3v= 8, combine like terms by adding 8v and 3v

11v-3= 8, add three to both sides

11v= 11, divide both sides by 11

v=1

-v+3v=4, combine like terms by adding -v and -3v

2v= 4, divide both sides by 2

v= 2
