Answer

The solution is $(1,4)$.

Work Step by Step

You are given the equations $14x-2y=6$ and $6y-9x=15$. Wrtite each equation in $y=mx+b$ form: $14x-2y=6$ $-2y=-14x+6$ $y=7x-3$ The slope is $7$ and the y-intercept is $-3$. Graph the equation, this is the red line. $6y-9x=15$ $6y=9x+15$ $y=\dfrac{3}{2}x+{\dfrac{5}{2}}$ The slope is $\dfrac{3}{2}$ and the y-intercept is $\frac{5}{2}$.Graph the equation,this is the blue line. The lines intersect at $(1,4)$ which is the solution.
