4x+3y=1,5x+3y=8

Solution

4 x + 3 y = 1, 5 x + 3 y = 8

Solution

x = 7, y = - 9

Solution steps

[4 x + 3 y = 1 5 x + 3 y = 8]

Isolate

x

for

4 x + 3 y = 1 : x = \frac{1 - 3 y}{4}

Substitute

x = \frac{1 - 3 y}{4}

[5 \cdot \frac{1 - 3 y}{4} + 3 y = 8]

Simplify

[\frac{5 - 3 y}{4} = 8]

Isolate

y

for

\frac{5 - 3 y}{4} = 8 : y = - 9

For

x = \frac{1 - 3 y}{4}

Substitute

y = - 9

x = \frac{1 - 3 ( - 9 )}{4}

\frac{1 - 3 ( - 9 )}{4} = 7

x = 7

The solutions to the system of equations are:

x = 7, y = - 9
