(11)2x+y=8,x-2y=-1

(11) 2 x + y = 8, x - 2 y = - 1

x = \frac{1}{3}, y = \frac{2}{3}

Solution steps

[(11) \cdot 2 x + y = 8 x - 2 y = - 1]

Isolate

x

for

(11) 2 x + y = 8 : x = \frac{8 - y}{22}

Substitute

x = \frac{8 - y}{22}

[\frac{8 - y}{22} - 2 y = - 1]

Simplify

[\frac{8 - 45 y}{22} = - 1]

Isolate

y

for

\frac{8 - 45 y}{22} = - 1 : y = \frac{2}{3}

For

x = \frac{8 - y}{22}

Substitute

y = \frac{2}{3}

x = \frac{8 - \frac{2}{3}}{22}

\frac{8 - \frac{2}{3}}{22} = \frac{1}{3}

x = \frac{1}{3}

The solutions to the system of equations are:

x = \frac{1}{3}, y = \frac{2}{3}

b = 12, a = 9

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

17 x + 23 y = 57, 23 x + 17 y = 63

2 x + y + 3 z = 6, 5 x - 2 y + 3 z = 6

2 y + x = 1, 1 y + x = 7
