Answer:
x=142, y=-360. (142, -360).
Step-by-step explanation:
5x+2y=-10
3x+y=66
----------------
5x+2y=-10
-2(3x+y)=-2*66
-----------------------
5x+2y=-10
-6x-2y=-132
-------------------
-x=-142
x=142
3(142)+y=66
426+y=66
y=66-426
y=-360
Answer:
1- 5x+2y+−2y=−10+−2y
5x=−2y−10
[tex]\frac{5}{5}[/tex]= [tex]\frac{-2y-10}{5}[/tex]
x= [tex]\frac{-2}{5}y-2[/tex]
2- 3x+y+−y=66+−y
3x=−y+66
[tex]\frac{3x}{3} = \frac{-y+66}{3}[/tex]
[tex]x=\frac{-1}{3}y+22[/tex]
