Given is three linear equation in three variables. We can solve for y by substituting the value of z = 3 into the second equation.
How to solve linear equations in three variables?
To solve the linear equations in three variables, follow the below steps:
- Take any two equations and solve it for one variable
- Again take another two pair of equations and solve for the same variable
- We have a system of two equations with two unknown variables. Solve the two equations
- Again substitute the evaluated values of the variables into any of the original equations and solve for unknown variables.
Solving for y :-
z = 3
2y + 2z = 10
2y + 2 * 3 = 10
2y + 6 = 10
2y = 4
y = 2
