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
+ –12x + 10y = –62
–11y = 22
y = –2
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?
