3x-y=64,5x-4y=14

3 x - y = 64, 5 x - 4 y = 14

x = \frac{242}{7}, y = \frac{278}{7}

Solution steps

[3 x - y = 64 5 x - 4 y = 14]

Isolate

x

for

3 x - y = 64 : x = \frac{64 + y}{3}

Substitute

x = \frac{64 + y}{3}

[5 \cdot \frac{64 + y}{3} - 4 y = 14]

Simplify

[\frac{320 - 7 y}{3} = 14]

Isolate

y

for

\frac{320 - 7 y}{3} = 14 : y = \frac{278}{7}

For

x = \frac{64 + y}{3}

Substitute

y = \frac{278}{7}

x = \frac{64 + \frac{278}{7}}{3}

\frac{64 + \frac{278}{7}}{3} = \frac{242}{7}

x = \frac{242}{7}

The solutions to the system of equations are:

x = \frac{242}{7}, y = \frac{278}{7}

2 x + y + z = 4, x + y + 2 z = 4, x - y - z = - 1

\frac{4}{3} x - y = 2, 2 x - y = 3

5 x + 2 y = 13, 2 x + 6 y = 26

2 x = 18 - 4 y, 3 x = 7 y - 12

3 x + 4 y = 13, 4 x + 3 x = 15
