(8x n) + 15=7 : 7-15= (-8), (-8)divided by 8= (-1) : n=(-1) : When you have problems like this it helps to work them backwards. Hope you understand this.

Consider this system of equations. Which equation represents the first equation written in slope-intercept form?
vlada-n [284]

Answer:

y= 5/2x - 5

Step-by-step explanation:

5x   -   2y   =   10

-5x                  -5x (Subtract both sides by 5x to leave y by itself)

-2y = -5x + 10

-2y/-2 = -5/-2 + 10/-2

(Divide both sides by -2 to leave y with no coefficient. -5/-2 = 5/2 because there are two negatives. 10/-2 = -5.

y = 5/2 - 5
