Answer:
thus, x=-34 and y=170/-3
Step-by-step explanation:
4((1/4)*x-(3/4)*y)=34
x-3y=136
24((3/4)*x+(1/8)*y)=12
18x+3y=-288
4x-3y=34⇒x-3y=136
18x+3y=12⇒18x+3y=-288
lets solve 4x-3y=34⇒x-3y=136 first:
4x-3y=34
x-3y=136
4x-3y=34
-x+3y=-136
3x=-102
x=-102/3
x=-34
lets plug in x to one of the equations, since both equations are equal to each other:
4x-3y=34
4(-34)-3y=34
-136-3y=34
-3y=170
y=170/-3
now lets solve: 18x+3y=12⇒18x+3y=-288
18x+3y=12
18x+3y=-288
18x+3y=12
-18x-3y=288
0[tex]\neq[/tex]300
so, this system doesn't work
thus, x=-34 and y=170/-3
