PLEASE HELP ASAP. I NEED TO UNDERSTAND THIS, 30 POINTS 6TH GRADE MATH

Answer:(2,7)Step-by-step explanation:Since the two equations are both set equal to y.  I would use substitution.y = 8x-9y = 4x-1Substitute the second equation in for y into the first equation4x-1 = 8x-9Subtract 4x from each side4x-4x-1 = 8x-4x-9-1 = 4x-9Add 9 to each side-1 +9 = 4x-9+98 =4xDivide each side by 48/4 =4x/42 =xBut we still need to find yy =4x-1y = 4(2) -1y = 8-1y =7The solution is (2,7)When we graph the two lines, the will cross at (2,7) which is the solution to the system of equations
