The answer for this problem would be 7x+6
Let's solve this problem step-by-step.
4x−3+3x+9
=4x+−3+3x+9
Step 1: Combine Like Terms.
=4x+−3+3x+9
=(4x+3x)+(−3+9)
So, the answer for this problem would be 7x+6.
Answer:
look at the picture I sent
If you divid 8.4 x 107 and 3 x 103 you should get 2.8 x 104
4 to 7......add them = 11
4/11 * 33 = 132/11 = 12
7/11 * 33 = 231/11 = 21
The two equations should be x+y=45 and 1.2x+y=52. Plug in x=35 y=10 into the second equation... then plug in x=25 and y=20 in the second equation
