11x-8y=27,3x+5y=-7

Solution

11 x - 8 y = 27, 3 x + 5 y = - 7

Solution

x = 1, y = - 2

Solution steps

[11 x - 8 y = 27 3 x + 5 y = - 7]

Isolate

x

for

11 x - 8 y = 27 : x = \frac{27 + 8 y}{11}

Substitute

x = \frac{27 + 8 y}{11}

[3 \cdot \frac{27 + 8 y}{11} + 5 y = - 7]

Simplify

[\frac{81 + 79 y}{11} = - 7]

Isolate

y

for

\frac{81 + 79 y}{11} = - 7 : y = - 2

For

x = \frac{27 + 8 y}{11}

Substitute

y = - 2

x = \frac{27 + 8 ( - 2 )}{11}

\frac{27 + 8 ( - 2 )}{11} = 1

x = 1

The solutions to the system of equations are:

x = 1, y = - 2

Popular Examples

y= 1/4 x^4-2,x^0=-1

y = \frac{1}{4} x^{4} - 2, x^{0} = - 1

x+2y=4,2x+4y=12

x + 2 y = 4, 2 x + 4 y = 12

5x+6y=15,7x+8y=20.4

5 x + 6 y = 15, 7 x + 8 y = 20.4

4 x - 3 y = 1, x + 3 y = 4

6 m/((m+222))*100=10,m=7

6 \frac{m}{( m + 222 )} \cdot 100 = 10, m = 7
