Answer:
Y = -5/3 + 2/3x
Step-by-step explanation:
subtract x to the other side
Then divide the equation by -3
First, we must subtract
57
-
26
______
31
Second, we isolate the variable!
X + 0 = 31 - 5
X+0 = 26
X=26
Finally,Plug it in
26 + 5 = 57 - 26
26 + 5 = 31
31 = 31
Check
Hope I helped!
Good Luck!
