Rewrite the equation using the properties of logarithms:
e^ln(x+3) = e^7
Exponentiation and ln are inverse functions so the equation simplifies to:
x + 3 = e^7
Subtract 3 from both sides:
x = e^7 -3
Raise e to the power of 7 and subtract 3 from that:
x = 1093.633 ( Rounded to the nearest hundredth).

Step-by-step explanation:
Answer: x = 27
Step-by-step explanation:
2x+3x+45=180º because all of the angles of a triangle add up to 180
5x=180-45
5x=135
x=135/5
x=27
