PLEASE HELP FAST
Solve the system of equations using the substitution method. y=2x-1 y=3x+3 Choose the ordered pair that solves both equations. (2,5) (4,7) (-1,3) (-4, -9)

-4,-9 I took the test and got the same answer.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
