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

Simplify by dividing negative three over eight divided by five over nine.
goblinko [34]

Answer:

\frac{-27}{40}

Step-by-step explanation:

First we need to write in correct form :

\frac{-3}{8}:\frac{5}{9}

We know how to divide fractions. If we can divide numerator by numerator, denominator by denominator, we just do it. In this example we can not do that.

So, we rewrite first fraction and multiply by reciprocal second ( numerator and denominator change place)

\frac{-3}{8} *\frac{9}{5}

Now, multiply numerator by numerator, denominator by denominator :

\frac{-27}{40}
