Question

3x - 4y = -22
10x + 8y = 12

Answer 1

3x-4y=-22

10x+8y=12

(3x-4y=-22) x 2--------->. 6x-8y=-44

10x+8y+6x-8y=12-44

16x=-32

x=-2

3(-2)-4y=-22

-6-4y=-22

-4y=-16

y=4

(ps: I don't know what you actually want, so I sloved both x and y.)

x= - 2,

y= 4

Answer 2

10x + 8y + 6x - 8y = 12 - 44
16x = -32
x = -2
sub in x = -2
-6 - 4y = -22
-4y = 16
y = -4
