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

Solution

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

Solution

x = - 3, y = 5

Solution steps

[x + y = 2 2 x + 3 y = 9]

Isolate

x

for

x + y = 2 : x = 2 - y

Substitute

x = 2 - y

[2 (2 - y) + 3 y = 9]

Simplify

[4 + y = 9]

Isolate

y

for

4 + y = 9 : y = 5

For

x = 2 - y

Substitute

y = 5

x = 2 - 5

Simplify

x = - 3

The solutions to the system of equations are:

x = - 3, y = 5

10 x + y = 51, 0 y + x = 14

3 y - 4 z = 8, 2 y - z = 9

a=-1, 3/15 b=-2, 0/26 c=-7/10

a = - 1, \frac{3}{15} b = - 2, \frac{0}{26} c = - \frac{7}{10}

x-y=3, x/3+y/2 =6

x - y = 3, \frac{x}{3} + \frac{y}{2} = 6

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