2y = 4x - 16 5y = 4x + 8 Subtract the first equation from the second: 3y = 24 so that y = 8 Substitute this into the first equation: 16 = 4x - 16 ie 32 = 4x so that x = 8 So the solution is (8, 8)
If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8
I can't tell what sign is before 5y, so I'll assume +. 4x+5y=7. Double this is 8x+10y=14, triple is 12x+15y=21. etc
This is not an equation since there is no equals sign. This means it is an expression, which can't be solved, only simplified. Even if it were an equation, there are two variables in this expression, so without knowing the values for both variables, we would not know if 67 is a solution.
4x + 5y = -8 is an equation with two variables. While you can solve for y = something, you won't come up with a single number. For example, 4x + 5y = -8 5y = -4x - 8 y = -4x/5 - 8/5. And you can do the same for x = something in terms of y.
4x-5y = 13 -5y = -4x+13 y = 4/5x-13/5 Slope = 4/5 or 0.8
2y = 4x - 16 5y = 4x + 8 Subtract the first equation from the second: 3y = 24 so that y = 8 Substitute this into the first equation: 16 = 4x - 16 ie 32 = 4x so that x = 8 So the solution is (8, 8)
If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8
Oh, dude, that's like super easy. So, to find y, you just divide both sides by 5, and you get y = 7. Boom, equation solved! Math is like a piece of cake, right?

The standard form, which is the form that can be generalised to 3 or more dimensional spaces, is 4x + 5y - 13 = 0
5y = 4x - 35 Divide each side of the equation by 5 : y = 4/5 x - 7
4x+5y = 20 5y = -4x+20 y = -4/5x+4 So the slope is -4/5 or as -0.8 and the y intercept is 4
The solution of the system of the two equations, 4x - y = 33 and 5y = 24 may be found by first solving the second equation for y: y = 24/5. then substituting this value into the first equation to produce 4x - (24/5) = 33, or x = [33 + (24/5)]/4 = [(189/5)/4] = (189/20).
Yes, generelly if there are no exponents greater than 1, it is a linear equation. in this case you can rearrange the equation to be: 4x-5y=10 ==> 4x-10 = 5y ==> 4/5x-2=y y=mx+b m=slope b=y-intercept slope = 4/5 y-intercept = -2
