x+y does not equal 10, which can be written x+y ~= 10 or x+y != 10.
2x+y = 10 x +y = 4 Subtract bottom equation from top equation: x = 6 Substitute the value of x into the equations to find the value of y: x = 6 and y = -2
9 plus 7 equals 144. Generally, x plus y = x(x+y).
x = -8, y = 10
choose the negation of this statement. x plus y equals 10
If x equals 10 and y equals 10, then 9x plus 8y equals 170.

y = 10. easy!
x+y does not equal 10, which can be written x+y ~= 10 or x+y != 10.
x = -4 and y = 2
y=10
The values are: x = -6 and y = 10
y=x-2
