10x-4y=24
How do I solve this!?

Set x = 0, solve for y.
10(0) - 4y = 24
-4y = 24
y = -6
(0, -6) is a solution.
Also, you can set y = 0
10x -4(0) = 24
10x =24
x = 2.4
(2.4, 0) is also a solution.
I'm not 100% certain that that is what you were looking for...hope it helps!

Y intercept
x = 0
10x - 4y = 24
10(0) - 4y = 24
0 - 4y = 24
- 4y = 24
Divide both sides of the equation by - 4
- 4y / - 4 = 24 / - 4
y = - 24/4
y = - 6
- - - - - - - - -
x intercept
y = 0
10x - 4y = 24
10x - 4(0) = 24
10x - 0 = 24
10x = 24
Divide both sides of the equation by 10
10x / 10 = 24 / 10
x = 24/ 10
simplify
x = 12/5
x = 2 2/5
x = 2.4

If you have 2 variables, you need at least 2 equations. Other wise;
x = (24+4y)/10 = 0.4y + 2.4
or
y = (24-10x)/-4 = 2.5x - 6

x=4 and y=4

The best you can do is solve for y in terms of x or x in terms of y:
y = 2.5x - 6
x = 0.4y + 2.4
