More than one way.
R1 plus R3:
R2 plus R3:
Work with the system:
-
Multiply the second equation here by 5 and subtract from first equation.
-
-
I would continue using this system to find y, also using elimination step. This time, multiply second equation by 3...
Choosing to continue in Elimination would be more effort than is justified. Take your now found values for y and z, and take either of the original equations and solve for x.
