Solve by Substitution 2x+5y=-4 , 3x-y=11

2 x + 5 y = - 4, 3 x - y = 11

x = 3, y = - 2

Solution steps

[2 x + 5 y = - 4 3 x - y = 11]

Isolate

x

for

2 x + 5 y = - 4 : x = \frac{- 4 - 5 y}{2}

Substitute

x = \frac{- 4 - 5 y}{2}

[3 \cdot \frac{- 4 - 5 y}{2} - y = 11]

Simplify

[\frac{- 12 - 17 y}{2} = 11]

Isolate

y

for

\frac{- 12 - 17 y}{2} = 11 : y = - 2

For

x = \frac{- 4 - 5 y}{2}

Substitute

y = - 2

x = \frac{- 4 - 5 ( - 2 )}{2}

\frac{- 4 - 5 ( - 2 )}{2} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 2

\frac{22}{( 2 )}

75 x^{3}

64 x^{4}

x^{\frac{1}{2}}

\frac{26}{50}
