Answer:
(x,y)=(4,6)
Step-by-step explanation:
3x+4y=36
y=-1/2 x+8
step 1: substitute the value of y
[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]
step 2: solve equation for x
[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]
3x-2x+32=36
x+32=36
x=36-32
x=4
step 3: substitute the value of x
[tex]y=-\frac{1}{2} (4)+8[/tex]
Step 4: solve equation for y
[tex]y=-\frac{1}{2} (4)+8[/tex]
y=-2+8
y=6
there for the answer is
(x,y)=(4,6)
