4x-2y=10,y=-2x-5

Solution

4 x - 2 y = 10, y = - 2 x - 5

Solution

x = 0, y = - 5

Solution steps

[4 x - 2 y = 10 y = - 2 x - 5]

Substitute

y = - 2 x - 5

[4 x - 2 (- 2 x - 5) = 10]

Simplify

[8 x + 10 = 10]

Isolate

x

for

8 x + 10 = 10 : x = 0

For

y = - 2 x - 5

Substitute

x = 0

y = - 2 \cdot 0 - 5

Simplify

y = - 5

The solutions to the system of equations are:

x = 0, y = - 5

Popular Examples

2x+3y=23,5x-20=8y

2 x + 3 y = 23, 5 x - 20 = 8 y

2x-2y=1,3x+5y=11

2 x - 2 y = 1, 3 x + 5 y = 11

2x=3,y-142y=x+8

2 x = 3, y - 142 y = x + 8

- x + y = 7, 2 x + 2 y = 2

2x=5,y+43x-2y+16=0

2 x = 5, y + 43 x - 2 y + 16 = 0
