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
