Solve the system of equations below. x − y = 6 3x − 2y = 22

The solution for system of equations x-y=6 ,3 x-2 y=22 is x = 10 and y = 4

Solution:

Using substitution method of algebraic equations,

x - y = 6 equation 1

3x - 2y = 22 equation 2

Multiplying equation 1 by 2, equation 1 becomes

2 x - 2 y = 12

Multiplying equation 2 by -1, equation 2 becomes,

-3 x + 2 y = -22

Solving,

2 x - 2 y = 12

-3 x + 2 y = -22

-x = -10

x = 10

Substitute  x = 10 in equation 1, 10 - y = 6

y  = 10 -6

y = 4
