Solve the linear system by substitution
WebThe substitution method is a technique for solving systems of linear equations. ... or you can add or subtract based on whether the fraction is positive or negative. All in all, the way … WebApr 24, 2024 · Start by adding 72 to both sides of the equation to give you 14x = 70. Divide both sides by 14 to give you x = 5. Take this value for x and put it into one of the original equations. This would give you 4 * 5 + y = 24 if you use the second equation. Solve for y. In this example, 20 + y = 24. Subtract 20 from both sides to give you y = 4.
