Get it in linear shape.
3X + 4Y = 120
4Y = -3X + 120
Y = -3/4X + 30
a line.
Slope = -3/4
y-intercept = 30
x-intercept = 40.
And that's as far as you can go. This doesn't "solve" anything. A 'solution' means
numbers for the variables that make the equation a true statement. You found a
line, and the (x, y) coordinates at every point on the line make the equation a true
statement. There are an infinite number of them.
An equation with two variables doesn't have a 'solution'. Its graph is a line.
Two equations with two variables have a solution ... the solution is the point
where the graphs (lines) of both of them intersect.
