x+4y=10,3x+7y=25

Solution

x + 4 y = 10, 3 x + 7 y = 25

Solution

x = 6, y = 1

Solution steps

[x + 4 y = 10 3 x + 7 y = 25]

Isolate

x

for

x + 4 y = 10 : x = 10 - 4 y

Substitute

x = 10 - 4 y

[3 (10 - 4 y) + 7 y = 25]

Simplify

[30 - 5 y = 25]

Isolate

y

for

30 - 5 y = 25 : y = 1

For

x = 10 - 4 y

Substitute

y = 1

x = 10 - 4 \cdot 1

Simplify

x = 6

The solutions to the system of equations are:

x = 6, y = 1

Popular Examples

x - y = 4, x = 3 y

5x-3y+4z=-7,2x+5z=3,7y+2z=12

5 x - 3 y + 4 z = - 7, 2 x + 5 z = 3, 7 y + 2 z = 12

x - 2 y = - 2 x - 4, y = 2

4x-y=30,6x+y=35

4 x - y = 30, 6 x + y = 35

x+y+2z=1,2x+2y+3z=2

x + y + 2 z = 1, 2 x + 2 y + 3 z = 2
