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

Solution

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

Solution

x = 1, y = 2

Solution steps

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

Isolate

x

for

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

Substitute

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

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

Simplify

[\frac{12 - y}{2} = 5]

Isolate

y

for

\frac{12 - y}{2} = 5 : y = 2

For

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

Substitute

y = 2

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

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = 2

- 17 x + 13 y = 43, 13 x - 17 y = - 47

5x+7y=1,6*3x+8y=12

5 x + 7 y = 1, 6 \cdot 3 x + 8 y = 12

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

x = y + 5, x + y = 31

9x-7y=-52,5x+3y=-22

9 x - 7 y = - 52, 5 x + 3 y = - 22
