Question

5x + 2y = -10 3x + y = 66 please show work

Answer 1

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 2

Answer:

1- 5x+2y+−2y=−10+−2y

5x=−2y−10

$\frac{5}{5}$= $\frac{-2y-10}{5}$

x= $\frac{-2}{5}y-2$

2-  3x+y+−y=66+−y

3x=−y+66

$\frac{3x}{3} = \frac{-y+66}{3}$

$x=\frac{-1}{3}y+22$
