Math is a subject that can be difficult for many people to understand. However, with a little practice, it can be easy to learn and even enjoyable.
There are also many YouTube videos that can show you how to Solve three linear equations.
Substitute z = 3 into equation (1). Substitute x = 4 and z = 3 into equation (2). Use the original equations to check the solution (the check is left to you). The solution is x = 4, y = –2, z = 3.
