y= 4/5 x+8,2x+y=-6

Solution

y = \frac{4}{5} x + 8, 2 x + y = - 6

Solution

x = - 5, y = 4

Solution steps

[y = \frac{4}{5} x + 8 2 x + y = - 6]

Substitute

y = \frac{4}{5} x + 8

[2 x + \frac{4}{5} x + 8 = - 6]

Simplify

[\frac{14}{5} x + 8 = - 6]

Isolate

x

for

\frac{14}{5} x + 8 = - 6 : x = - 5

For

y = \frac{4}{5} x + 8

Substitute

x = - 5

y = \frac{4}{5} (- 5) + 8

\frac{4}{5} (- 5) + 8 = 4

y = 4

The solutions to the system of equations are:

x = - 5, y = 4

Popular Examples

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

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

2x+3y+b=0,4x=3y

2 x + 3 y + b = 0, 4 x = 3 y

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

x + y = 9, x - y = 5

x + y = 9, x - y = 3
