The equation is -2y + 16 = 10
If you mean 10+2y = 16 then the solution is y = 3
10-y=2y+3 10-3=2y+y 7=3y 7/3=y
Here's how it is:2y + 10 = 5y - 4ySolution:2y + 10 = 1y (subtract 5y and 4y)10 = 1y - 2y10 = -1y-1(10 = -1y)y = -10
4x+2y = 20 2y = -4x+20 y = -2x+10
2y+5y=10 7y=10 y=10/7
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
The equation is -2y + 16 = 10
y = 5
If you mean 10+2y = 16 then the solution is y = 3
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
10-y=2y+3 10-3=2y+y 7=3y 7/3=y
Here's how it is:2y + 10 = 5y - 4ySolution:2y + 10 = 1y (subtract 5y and 4y)10 = 1y - 2y10 = -1y-1(10 = -1y)y = -10
4x+2y = 20 2y = -4x+20 y = -2x+10
4x-2y+3x+2y When simplified: 7x
10x + 41y - 142x + 2y = 10x - 142x + 41y + 2y = (10 -142)x + (41 + 2)y = -132x + 43y
2Y + 10 = 28 subtract 10 from both sides 2Y + 10 - 10 = 28 - 10 2Y = 18 divide both sides by 2 Y = 9 -------- check 2(9) + 10 = 28 18 + 10 = 28 28 = 28 checks
