Use the substitution method to solve each linear system. 4x - 3y = -13,-2x + y = 4
Contact [7]

Answer:

The solutions to the system of equations are:

x=\frac{1}{2},\:y=5

Step-by-step explanation:

Given the system of the equations

\begin{bmatrix}4x-3y=-13\\ -2x+y=4\end{bmatrix}

Isolate x for for 4x-3y=-13

4x-3y=-13

4x=-13+3y

Divide both sides by 4

x=\frac{-13+3y}{4}

substitute y=5

x=\frac{-13+3\cdot \:5}{4}

x=\frac{1}{2}

The solutions to the system of equations are:

x=\frac{1}{2},\:y=5
