X+y=12
8x+10y=102
8x+8y=96
8x+10y=102 _
-2y= -6
y=3
x+y=12
x=12- 3
x=9
or
8x+10y=102
8x+30=102
8x=102-30
8x=72
x=9
55
—— x + 35/6
24
this is the final answer
Umm hi how are you today keep going and dont cheet h
Answer:
85 and -31
step-by-step:
x + y = 54
x - y = 116
solve for x in first equation
x = 54 - y
sub into second equation
54 - y - y = 116
54 - 2y = 116
-2y = 62
y = -31
sub in x equation
x = 54 - (-31)
x = 85
