Answer

$(\dfrac{5}{2},-2)$

Work Step by Step

Since, we have first equation: $4x+3y=4$ and second equation: $y=2x-7$ From the first equation, we have $4x+3(2x-7)=4$ or, $4x+6x-21=4$ or, $10x=25$ Thus, $x=\dfrac{5}{2}$ From the second equation, we have $y=2(\dfrac{5}{2})-7$ or, $y=-2$ Hence, the solution is: $(\dfrac{5}{2},-2)$
