Let's solve for x.
120+25x+4y=180
Step 1: Add -120 to both sides.
25x+4y+120+−120=
180+−120
25x+4y=60
Step 2: Add -4y to both sides.
25x+4y+−4y=60+−4y
25x=−4y+60
Step 3: Divide both sides by 25.
25x/25=−4y+60/25
x=−4/25(y)+12/5
Let's solve for y.
120+25x+4y=180
Step 1: Add -120 to both sides.
25x+4y+120+−120=
180+−120
25x+4y=60
Step 2: Add -25x to both sides.
25x+4y+−25x=60+−25x
4y=−25x+60
Step 3: Divide both sides by 4.
4y/4=−25x+60/4(y)=−25/4(x)+15
