2x plus 3y is not an equation, it is an expression.
Five is the coefficient of x.
-4
5x + 3y - 2 - x + y + 2 = 4x + 4y = 4(x + y)
Solve for y 3y=-7x+9 y=-7/3x+3 the slope is the coefficient of x in this case, it is -7/3

I'm not sure why this is labeled as calculus; it's just algebra. You take the first coefficient and the 2nd coefficient and add them. 1y x 3y = (1+3)y = 4y
4x + 3y = 12 3y = -4x + 12 y = -4/3x + 4 The slope is therefore -4/3 (the coefficient of the x term) The y intercept is 4 (the value of y when x = 0)

x=4 y=0
-4
5x + 3y - 2 - x + y + 2 = 4x + 4y = 4(x + y)
If you mean: -x+3y = 6 and x+3y = 18 then by substitution x = 6 and y = 4
X + 3y - 2y + 3y = X + (3-2+3)y = X + 4y
-x+3y+6x-6y=5x-3y
Solve for y 3y=-7x+9 y=-7/3x+3 the slope is the coefficient of x in this case, it is -7/3
