x+y=8,x-y=2

Solution

x + y = 8, x - y = 2

Solution

x = 5, y = 3

Solution steps

[x + y = 8 x - y = 2]

Isolate

x

for

x + y = 8 : x = 8 - y

Substitute

x = 8 - y

[8 - y - y = 2]

Simplify

[8 - 2 y = 2]

Isolate

y

for

8 - 2 y = 2 : y = 3

For

x = 8 - y

Substitute

y = 3

x = 8 - 3

Simplify

x = 5

The solutions to the system of equations are:

x = 5, y = 3

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

x/2+y/3 =9, x/5-y/4 =-1

\frac{x}{2} + \frac{y}{3} = 9, \frac{x}{5} - \frac{y}{4} = - 1

2x-3y=8,3x+y=-10

2 x - 3 y = 8, 3 x + y = - 10
