High School students a & b

1.) 8x+8y=240

1x+(-2)4y=(-2)54

8x+8y=240

-2x+-8y=-108

6x=132

6x/6=132/6

x=22

2.) 8(22)+8y=240

176+8y=240

-176 -176

6.) 8y=64

8y/8=64/8

y=8

3.) 8(22)+8(8)=240 4.) 1(22)+4(8)=54

176+64=240 22+32=54

240=240 Solution 54=54

1: solve for x

2: solve for y

3: find solution

4: check solution
