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 plus 2y can be expressed mathematically as (3x + 2y).

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

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

11x + 2y

2y = -10y = -58 - 2x - 2(-5) = -108 - 2x + 10 = -10-2x = -10 - 182x = 28x = 14Check:2y = 8 - 2x - 2y = -102(-5) = 8 - 2(14) - 2(-5) = -10-10 = 8 - 28 + 10 = -10-10 = -20 + 10 = -10-10 = -10 = -10

It is 12x + 11y + 9.

1y

The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).

4x + 2y = 20 2y = -4x + 20 y = -2x + 10.......but you may also write it as y = 10 - 2x.

10-2y

10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
