Answer:
(-2,3)
Step-by-step explanation:
4x+5y =7
y = 3x+9
Substitute the second equation into the first equation
4x +5(3x+9) = 7
Distribute
4x + 15x + 45 = 7
Combine like terms
19x +45 =7
Subtract 45 from each side
19x +45-45 = 7-45
19x = -38
Divide by 19
19x/19 = -38/19
x = -2
Now we need to find y
y = 3x+9
Putting in x=-2
y = 3(-2) +9
y = -6 +9
y = 3
