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?
