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

Solution

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

Solution

x = - 1, y = 5

Solution steps

[3 x + y = 2 3 x + 2 y = 7]

Isolate

x

for

3 x + y = 2 : x = \frac{2 - y}{3}

Substitute

x = \frac{2 - y}{3}

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

Simplify

[2 + y = 7]

Isolate

y

for

2 + y = 7 : y = 5

For

x = \frac{2 - y}{3}

Substitute

y = 5

x = \frac{2 - 5}{3}

\frac{2 - 5}{3} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = 5

Popular Examples

(x - 7)^{2} = 3 y, x = 0

1/7 x+1/6 y=3, 1/2 x-1/3 y=5

\frac{1}{7} x + \frac{1}{6} y = 3, \frac{1}{2} x - \frac{1}{3} y = 5

3 x + y = 7, 4 x + 3 y = 6

x-4y=2,0.8-3x+6y=-2.4

x - 4 y = 2, 0.8 - 3 x + 6 y = - 2.4

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