3x - y = 0
5x + 2y = 22
Multiply both sides by 2.
6x - 2y = 0
5x + 2y = 22
Eliminate one variable by adding the equations
11x = 22
Divide both sides by 11
x = 2
Substitute the value of x into the equation.
3 x 2 - y = 0
Solve the equation
y = 6
Therefore,
x = 2
y = 6
5x + 2y = 22
Multiply both sides by 2.
6x - 2y = 0
5x + 2y = 22
Eliminate one variable by adding the equations
11x = 22
Divide both sides by 11
x = 2
Substitute the value of x into the equation.
3 x 2 - y = 0
Solve the equation
y = 6
Therefore,
x = 2
y = 6
