3x + y
3x plus 2y - 3 is an expression. There can be no answer to one expression and one linear equation in two variables.
3x - y = 3y = 2x + 2Put the value of y in the 1st equation:3x - y = 3 it will be -->3x - ( 2x + 2 ) = 33x - 2x - 2 = 3x - 2 = 3X = 5Put the value of X in the 2nd equation so as to find the value of Y :y = 2x + 2y = 2(5) + 2y = 10 + 2Y = 12
3x plus 2y can be expressed mathematically as (3x + 2y).
y=-3/2x + 1/2
3x + y
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
3x-2y+9+9y-x = 2x+7y+9
If you mean 3x+2y = -5 and -2x+3y = -5 then they are straight line equations
-3x + 2y = 8To get into slope intercept, we must set the equation equal to y2y = 3x + 8y = 3/2x + 8/2y = 3/2x + 4
3x plus 2y - 3 is an expression. There can be no answer to one expression and one linear equation in two variables.
3x - y = 3y = 2x + 2Put the value of y in the 1st equation:3x - y = 3 it will be -->3x - ( 2x + 2 ) = 33x - 2x - 2 = 3x - 2 = 3X = 5Put the value of X in the 2nd equation so as to find the value of Y :y = 2x + 2y = 2(5) + 2y = 10 + 2Y = 12

3x plus 2y can be expressed mathematically as (3x + 2y).
2. If x=5 & y =3 then: 3x + 2y = 3 x 5 + 2 x 3 = 15 + 6 = 21 2x + 3y = 2 x 5 + 3 x 3 = 10 + 9 = 19 ⇒ 3x+2y exceeds 2x+3y by 21 - 19 = 2. Alternatively: 3x+2y exceeds 2x+3y by: (3x+2y) - (2x + 3y) = 3x + 2y - 2x - 3y = x - y If x=5 & y=3 then this becomes: x - y = 5 - 3 = 2
y=-3/2x + 1/2
