You can put this solution on YOUR website!
First simplify your equation.
X and Y on the left hand side, constant on the right.
12x%2B15y%2B21=4x-5y%2B7
8x%2B20y%2B21=7
8x%2B20y=-14
.
.
.
x intercept occurs when y=0, set y=0 and solve for x.
8x%2B20y=-14
8x%2B20%280%29=-14
8x=-14
x=-14%2F8=-7%2F4
x intercept : x=-7/4, y=0.
.
.
.
y intercept occurs at x=0, set x=0 and solve for y.
8x%2B20y=-14
8%280%29%2B20y=-14
20y=-14
y=-14%2F20=-7%2F10
y intercept : x=0, y=-7/10.
