3x+4y=7,x+5y=17

Solution

3 x + 4 y = 7, x + 5 y = 17

Solution

x = - 3, y = 4

Solution steps

[3 x + 4 y = 7 x + 5 y = 17]

Isolate

x

for

3 x + 4 y = 7 : x = \frac{7 - 4 y}{3}

Substitute

x = \frac{7 - 4 y}{3}

[\frac{7 - 4 y}{3} + 5 y = 17]

Simplify

[\frac{7 + 11 y}{3} = 17]

Isolate

y

for

\frac{7 + 11 y}{3} = 17 : y = 4

For

x = \frac{7 - 4 y}{3}

Substitute

y = 4

x = \frac{7 - 4 \cdot 4}{3}

\frac{7 - 4 \cdot 4}{3} = - 3

x = - 3

The solutions to the system of equations are:

x = - 3, y = 4

Popular Examples

y-132x-5y=-30,x=2

y - 132 x - 5 y = - 30, x = 2

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

x/3+y=16,3x+y/2 = 61/2

\frac{x}{3} + y = 16, 3 x + \frac{y}{2} = \frac{61}{2}

2x+4y=22,2x+2y=15

2 x + 4 y = 22, 2 x + 2 y = 15

3x+4y=2,9x+16y=7

3 x + 4 y = 2, 9 x + 16 y = 7
