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

Solution

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

Solution

x = - 1, y = 2

Solution steps

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

Isolate

x

for

x + 3 y = 5 : x = 5 - 3 y

Substitute

x = 5 - 3 y

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

Simplify

[10 - 7 y = - 4]

Isolate

y

for

10 - 7 y = - 4 : y = 2

For

x = 5 - 3 y

Substitute

y = 2

x = 5 - 3 \cdot 2

Simplify

x = - 1

The solutions to the system of equations are:

x = - 1, y = 2

99 x + 101 y = 499, 101 x + 99 y = 501

6x+5y=62,4x-5y=8

6 x + 5 y = 62, 4 x - 5 y = 8

3x-y=10,2x+5y=1

3 x - y = 10, 2 x + 5 y = 1
