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

Solution

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

Solution

x = 5, y = 4

Solution steps

[x - y = 1 - x + 2 y = 3]

Isolate

x

for

x - y = 1 : x = 1 + y

Substitute

x = 1 + y

[- (1 + y) + 2 y = 3]

Simplify

[- 1 + y = 3]

Isolate

y

for

- 1 + y = 3 : y = 4

For

x = 1 + y

Substitute

y = 4

x = 1 + 4

Simplify

x = 5

The solutions to the system of equations are:

x = 5, y = 4

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

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

89x+91y=44,991x+89y=451

89 x + 91 y = 44, 991 x + 89 y = 451

2x-3y=10,0.4x-y=10

2 x - 3 y = 10, 0.4 x - y = 10

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

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

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