-10 -5x -2x = -3
Add 7x to both sides: -10 + 0x = 7x - 3 and then drop 0x
Add 3 to both sides: -7 = 7x
Divide both sides by 7: -1 = x
but you should just pay attention in school and you wouldn't need to ask this question.
try harder in school and don't be a fool.

If x+y = 3 and y times x = 2 then y = 1.
that is an equation of a line with a slope of 1 and y-intercept of -3 and x-intercept of 3
x equals 221
y = 12. It's the transitive property. y = 12 = 3x.
y=x y=6-x Set the two equations equal to each other to yield a solution: x=6-x 2x=6 x=3 x=3 will satisfy both equations, that is plugging in x=3 will give the same value for y y=(3)=3 y=6-(3)=3
