How to solve a 3 variable equation
WebSolution: Given, the equation is; 3 + x = 4 We can see, on the Left hand side, the variable x is present. Thus, we need to make the variable ‘x’ alone on LHS. Thus, by subtracting the 3 from LHS and RHS we get; 3 + x – 3 = 4 – 3 x = 1 Hence, the solution is x = 1. Verification: For x = 1 Taking LHS and proving it equal to RHS.
