x-4y=3,5x+5y=65

Solution

x - 4 y = 3, 5 x + 5 y = 65

Solution

x = 11, y = 2

Solution steps

[x - 4 y = 3 5 x + 5 y = 65]

Isolate

x

for

x - 4 y = 3 : x = 3 + 4 y

Substitute

x = 3 + 4 y

[5 (3 + 4 y) + 5 y = 65]

Simplify

[15 + 25 y = 65]

Isolate

y

for

15 + 25 y = 65 : y = 2

For

x = 3 + 4 y

Substitute

y = 2

x = 3 + 4 \cdot 2

Simplify

x = 11

The solutions to the system of equations are:

x = 11, y = 2

Popular Examples

x = - 2, y = - 5

3x+4y=-23,x=3y+1

3 x + 4 y = - 23, x = 3 y + 1

3 x + 5 y = 7, y = 2 x + 4

a = 3, c = 9

2x-5y=7,5x-2y=14

2 x - 5 y = 7, 5 x - 2 y = 14
