Answer:
87
Step-by-step explanation:
Found a great explanation + 1105p = £11.05
(x+4)+(x+4)
2(x+2(2)) the (2) would be the exponent for 2 in the second one.
If you would like to solve 4 + 3/5 * (15 + 2x) = 25 for x, you can do this using the following steps:
4 + 3/5 * (15 + 2x) = 25
3/5 * (15 + 2x) = 25 - 4
9 + 6/5 * x = 21
6/5 * x = 21 - 9
6/5 * x = 12 /*5/6
x = 12 * 5/6
x = 10
The correct result would be x = 10.
16 the answer is 16
7 is 5more than to see 2 plus 5 = 7 so 21 - 5 =16 GENIUS :3
