Answer: If you have to work it out then here's the explaining
Step-by-step explanation:
1. (2x+4) 3x10= 59. which is the given and you have to find the prove which is 9 so look at these steps carefully so you know how I got it.
2. 5x+14=59
3. 2x+4+3x+10=59 (I hope you can see that it's equal to 59 it don't change)
5x+14=59 and change it to 5x=59-14 now I got that because you have to change the sign and change what's at the end of the problem of 5x+14=59 which is 59 go to the right where 5x is at.
4. Then we subtracr 5x=59-14 which would give us.. 5x=45
5. You divide both sides by 5 *5x=45/5 which is 9.
