Answer:
y = -x +4
Step-by-step explanation:
2x+5y = 3y+8
Subtract 3y from each side
2x+5y-3y = 3y-3y+8
2x+2y = 8
Subtract 2x from each side
2x+2y -2x = -2x+8
2y = -2x+8
Divide by 2
2y/2 = -2x/2 +8/2
given that, y=2×7
y=14
and
x+y=5
x+14=5
x=5-14
x=9
x not equal to 5
x=7/3
3(x-4)=-5
3x-12=-5
3x=7
The solution is in the picture
b
21,736 divided by 143 is 157
