Solving for systems of linear equations
Weby - y = 9y - y. So 0 = 8y. divide both sides by 8 to get y = 0. plug that into your original equation to find out that when y = 0, x = 0. So there is one solution and it also explains why y can … Web12x + 7y = 218. The first equation can be multiplied by -12 and the second equation by 5 to eliminate x. Henrique began to solve a system of linear equations using the linear combination method. His work is shown below: 3 (4x - 7y = 28) → 12x - 21y = 84. -2 (6x - 5y = 31) → -12x + 10y = -62. 12x - 21y = 84.
