Question

Help! How do you solve for x and y in the equations 2x+5y=2 and 4x-2y+20=0???

Thank you so much for helping me!!!

Answer 1

Hope this helps

Solved for X

2x+5y=2Step 1: Add -5y to both sides.2x+5y+−5y=2+−5y2x=−5y+2Step 2: Divide both sides by 2.2x2=−5y+22x=−52y+1Answer:x=−52y+1
Solved for Y

2x+5y=2Step 1: Add -2x to both sides.2x+5y+−2x=2+−2x5y=−2x+2Step 2: Divide both sides by 5.5y5=−2x+25y=−25x+25Answer:y=−25x+25

Solved for X


4x−2y+20=0Step 1: Add -20 to both sides.4x−2y+20+−20=0+−204x−2y=−20Step 2: Add 2y to both sides.4x−2y+2y=−20+2y4x=2y−20Step 3: Divide both sides by 4.4x4=2y−204x=12y−5Answer:x=12y−5

Solved for Y


4x−2y+20=0Step 1: Add -20 to both sides.4x−2y+20+−20=0+−204x−2y=−20Step 2: Add -4x to both sides.4x−2y+−4x=−20+−4x−2y=−4x−20Step 3: Divide both sides by -2.−2y−2=−4x−20−2y=2x+10Answer:y=2x+10
