WebOne way you can do that is by multiplying the top equation by 5 and multiplying the bottom equation by 3 because then, you could easily cancel out the 15 (top equation) and the -15 (bottom equation) and solve the rest of the equation accordingly. >>> 5x + 3y = 12 4x - 5y = 17 5x + 15y = 12 4x - 15y = 17 5x = 12 4x = 17 9x = 29 x = ~3.22 (Then ... WebThe substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation. In this way, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved.
