<span>3[x + 3(4x – 5)] = 15x – 24
3x + 12x - 15 = 15x - 24
15x - 15 = 15x - 24

This angle is in the third quadrant
tan theta = -4 / -3 = 4/3 answer (and theta = 233.13 degrees)
Jiri’s age is 43
Pamela is 5 years younger mean
Mean Jiri is old 5 years, take number of Jiri age minus Pamela age.
-> J-5=P
The sum mean plus
P+J=81
Use substitution for the equation 1 to find the answer.
(J-5) +J=81
2J-5=81
2J=86
J=43
-5t+5t+2+8-8
-5t+5t=0 or t
2+8-8=2
t+2 is the final answer
