2x+y=8,x-y=1

Solution

2 x + y = 8, x - y = 1

Solution

x = 3, y = 2

Solution steps

[2 x + y = 8 x - y = 1]

Isolate

x

for

2 x + y = 8 : x = \frac{8 - y}{2}

Substitute

x = \frac{8 - y}{2}

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

Simplify

[\frac{8 - 3 y}{2} = 1]

Isolate

y

for

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

For

x = \frac{8 - y}{2}

Substitute

y = 2

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

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

x = 3

The solutions to the system of equations are:

x = 3, y = 2

27x+54y=21,6-22.5x+45y=90

27 x + 54 y = 21, 6 - 22.5 x + 45 y = 90

8y-8x=30,50x-12y=4

8 y - 8 x = 30, 50 x - 12 y = 4

x+3y=6,2x-3y=12

x + 3 y = 6, 2 x - 3 y = 12

3 x - y = - 3, 2 x + y = 8

3x+5y=21,4x-2y=2

3 x + 5 y = 21, 4 x - 2 y = 2
