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

Solution

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

Solution

x = \frac{11}{7}, y = \frac{17}{7}

Solution steps

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

Isolate

x

for

x + y = 4 : x = 4 - y

Substitute

x = 4 - y

[5 (4 - y) - 2 y = 3]

Simplify

[20 - 7 y = 3]

Isolate

y

for

20 - 7 y = 3 : y = \frac{17}{7}

For

x = 4 - y

Substitute

y = \frac{17}{7}

x = 4 - \frac{17}{7}

4 - \frac{17}{7} = \frac{11}{7}

x = \frac{11}{7}

The solutions to the system of equations are:

x = \frac{11}{7}, y = \frac{17}{7}

Popular Examples

x + 5 y = 11, 3 x - y = 1

x + y = 8, 3 x + y = 10

x - 53 x - y = 9, y = 2

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

2 x - 5 y = 0, x - y = 2
