1st eq.  4x +5y = 7

2nd eq.  y = 3x+9

 replace the value of y from 2nd eq for y in 1st eq.

4x +5(3x+9) = 7

now distribute:

4x + 15x + 45 = 7

 combine like terms:

19x + 45 = 7

subtract 45 from each side:

19x = -38

divide both sides by 19

x = -38/19 = -2


now use value of x in 2nd eq to solve for y

y = 3(-2) +9 = -6 + 9 = 3

x = -2, y = 3
