3x-4y=-7,5x-2y=0

Solution

3 x - 4 y = - 7, 5 x - 2 y = 0

Solution

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

Solution steps

[3 x - 4 y = - 7 5 x - 2 y = 0]

Isolate

x

for

3 x - 4 y = - 7 : x = \frac{- 7 + 4 y}{3}

Substitute

x = \frac{- 7 + 4 y}{3}

[5 \cdot \frac{- 7 + 4 y}{3} - 2 y = 0]

Simplify

[\frac{- 35 + 14 y}{3} = 0]

Isolate

y

for

\frac{- 35 + 14 y}{3} = 0 : y = \frac{5}{2}

For

x = \frac{- 7 + 4 y}{3}

Substitute

y = \frac{5}{2}

x = \frac{- 7 + 4 \cdot \frac{5}{2}}{3}

\frac{- 7 + 4 \cdot \frac{5}{2}}{3} = 1

x = 1

The solutions to the system of equations are:

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