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

Solution

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

Solution

x = 3, y = 7

Solution steps

[x + y = 10 - 2 x + y = 1]

Isolate

x

for

x + y = 10 : x = 10 - y

Substitute

x = 10 - y

[- 2 (10 - y) + y = 1]

Simplify

[- 20 + 3 y = 1]

Isolate

y

for

- 20 + 3 y = 1 : y = 7

For

x = 10 - y

Substitute

y = 7

x = 10 - 7

Simplify

x = 3

The solutions to the system of equations are:

x = 3, y = 7

3 x - 5 y - 19 = 0, - 7 x + 3 y + 1 = 0

9x+16y=7,4y-3x=0

9 x + 16 y = 7, 4 y - 3 x = 0

2x+3y=3,x+5y=-9

2 x + 3 y = 3, x + 5 y = - 9
