5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y

It's an expression in 'x' and 'y'.It may be simplified (cleaned up) to yield:7x + 2y - 2x + 3y =5x +5yor5 (x + y)

5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y

7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387

The given expression can be simplified to: 7x+4y

(14x-2y)+(7x-3y)+(-3x) = 14x-2y+7x-3y-3x =(14+7-3)x-(2+3)y =18x-5y

x = 3 and y = 0

Solve for y 3y=-7x+9 y=-7/3x+3 the slope is the coefficient of x in this case, it is -7/3

The expression can be simplified to: 7x+4y

The expression can be simplified to: 7x+4y

y=mx+b 7x+3y=21 3y=21-7x *****_ y=7-2.3x *****_ m= -2.3 negative

7x+3y where x=2 and y=9 can be written as (7*2)+(3*9) which can be simplified to (14)+(27), from there it's basic addition.
