Henrique began to solve a system of linear equations using the linear combination method. His work is shown below:
3(4x β 7y = 28) β 12x β 21y = 84
β2(6x β 5y = 31) β β12x + 10y = β62
12x β 21y = 84
+ β12x + 10y = β62
β11y = 22
y = β2
Complete the steps used to solve a system of linear equations by substituting the value of y into one of the original equations to find the value of x.
What is the solution to the system?
