5x-y=7,3x+2y=12

Solution

5 x - y = 7, 3 x + 2 y = 12

Solution

x = 2, y = 3

Solution steps

[5 x - y = 7 3 x + 2 y = 12]

Isolate

x

for

5 x - y = 7 : x = \frac{7 + y}{5}

Substitute

x = \frac{7 + y}{5}

[3 \cdot \frac{7 + y}{5} + 2 y = 12]

Simplify

[\frac{21 + 13 y}{5} = 12]

Isolate

y

for

\frac{21 + 13 y}{5} = 12 : y = 3

For

x = \frac{7 + y}{5}

Substitute

y = 3

x = \frac{7 + 3}{5}

\frac{7 + 3}{5} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = 3

2x-3y=5,5x+7y=-2

2 x - 3 y = 5, 5 x + 7 y = - 2

3x-4y=26,2x-3y=-19

3 x - 4 y = 26, 2 x - 3 y = - 19

x - y = 1, - x + 2 y = 3

-2x+y=8,x-4y=-5

- 2 x + y = 8, x - 4 y = - 5

89x+91y=44,991x+89y=451

89 x + 91 y = 44, 991 x + 89 y = 451
