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)
