7 = 2x + 15
<7
Subtract by 15
-8 = 2x
Divide by 2
-4 = x
<8
8 = 3x
divide by 3
8/3 = x
Answer:
15, -7 x=15 y=-7
Step-by-step explanation:
x+y=8, we'll come back to this
x-y=22, move y to the other side, x=y+22
now insert the value of x =(y+22) to the other equation like so, (y+22)+y=8, simplify
2y+22=8 2y=(-14), y=(-7)
Insert the value of y into the first equation again like so, x+(-7)=8, simplify
x=15
15, -7
