3x-y=4,-y+2x=1

Solution

3 x - y = 4, - y + 2 x = 1

Solution

x = 3, y = 5

Solution steps

[3 x - y = 4 - y + 2 x = 1]

Isolate

x

for

3 x - y = 4 : x = \frac{4 + y}{3}

Substitute

x = \frac{4 + y}{3}

[- y + 2 \cdot \frac{4 + y}{3} = 1]

Simplify

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

Isolate

y

for

\frac{8 - y}{3} = 1 : y = 5

For

x = \frac{4 + y}{3}

Substitute

y = 5

x = \frac{4 + 5}{3}

\frac{4 + 5}{3} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = 5

Popular Examples

5x+2y=24,4x+3y=29

5 x + 2 y = 24, 4 x + 3 y = 29

y = 2 x - 1, 2 y - x = 7

-2x+2y=-4,3x+3y=-18

- 2 x + 2 y = - 4, 3 x + 3 y = - 18

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

3x-4(y-2)=2,2x+3(y-3)=4

3 x - 4 (y - 2) = 2, 2 x + 3 (y - 3) = 4
