Solve the system of equations using addition
WebApr 24, 2024 · By Kathryn White. A system of linear equations involves two relationships with two variables in each relationship. By solving a system, you are finding where the two relationships are true at the same time, in other words, the point where the two lines cross. Methods for solving systems include substitution, elimination, and graphing. WebSolve the system by elimination. {x + y = 10 x − y = 12. Both equations are in standard form. The coefficients of y are already opposites. Add the two equations to eliminate y. The resulting equation has only 1 variable, x. Solve for x, the remaining variable. Substitute x = 11 into one of the original equations.
