Question

I just need the answers

Answer 1

x=4

Explanation:

start by canceling 4x on both sides.

x − 5 − 4 = 8 − 5x + 7

simplify x − 5 − 4 to x - 9

x - 9 = 8 - 5x + 7

simplify 8 - 5x + 7 to -5x + 15

x - 9 = -5x + 15

add 9 to both sides

x = -5x + 15 + 9

simplify -5x + 15 +9 to -5x + 24

x = -5x +24

add 5x to both sides

x + 5x = 24

simplify x + 5x to 6x

6x = 24

divide both sides by 6

x =
`(24)/(6)`

simplify
`(24)/(6)`

x = 4

Answer 2

x=4. y= 7/2----3.5

Explanation:

for B the answer could also he m=0, b=7/2 if you're looking for the function

if you want the alt version it could also be y=3 1/2/y=3.5
