Answer:
1) 4x-y=5
step :add y to the both sides
4x-y+y=5+y
4x=y+5
step 2:divide both sides by 4
4x y+5
—= —
4 4
x=1 5
—y+ —
4 4
answer:1 5
—y+ —
4 4
2) 2x+2y=2
step 1:add -2y to both sides
2x+2y+-2y=2+-2y
2x= -2y+2
step 2:divide both sides by 2
2x -2y+2
— = ——
2 2
x= -y+1
answer:-y+1
3) 3x+4y= -4
step 1:add -4y to both sides
3x+4y+-4y= -4+ -4y
3x= -4y-4
step2: divide both sides by 3
3x -4y-4
— = ——
3 3
answer: -4 -4
x= —y+ —
3 3
4) 2x+y=7
2x+y+-y=7-y
2x= -y+7
2x -y+7
— = —–
2 2
-1 7
x= —y+ —
2 2
-1 7
answer: x= — y+ —
2 2
5)4x-4
answer : 4(x-1)
6) 4x-y=4
4x-y+y=4+y
4x=y+4
4x y+4
— = ——
4 4
x= 1
— y+1
4
answer: 1
— y+1
7) x+2y=2
x+2y+-2y=2+-2y
x= -2y+2
answer: x= -2y+2
4
