3x+7y=11,3x-2y=-7

Solution

3 x + 7 y = 11, 3 x - 2 y = - 7

Solution

x = - 1, y = 2

Solution steps

[3 x + 7 y = 11 3 x - 2 y = - 7]

Isolate

x

for

3 x + 7 y = 11 : x = \frac{11 - 7 y}{3}

Substitute

x = \frac{11 - 7 y}{3}

[3 \cdot \frac{11 - 7 y}{3} - 2 y = - 7]

Simplify

[11 - 9 y = - 7]

Isolate

y

for

11 - 9 y = - 7 : y = 2

For

x = \frac{11 - 7 y}{3}

Substitute

y = 2

x = \frac{11 - 7 \cdot 2}{3}

\frac{11 - 7 \cdot 2}{3} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = 2

Popular Examples

x + 2 = 0, x^{2} = 6

x+3y=11,3(x-1)-5y=-68

x + 3 y = 11, 3 (x - 1) - 5 y = - 68

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

x=(x)+(x)+x,x=4

x = (x) + (x) + x, x = 4

2.5 c = 41.3, a = 3
