2x+1=10 (b/c divide both sides by 5
2x=9
x=4.5
Answer: 42
Step-by-step explanation:
First you have to subtract 450 from 6750 to get 6300
Second you have to figure out how many tax returns you have to make by dividing 6300 by 14 to get 450
Third you have to do 6300 / 42 to get 150 so if you times 150x 42 equals 6300.
For the first one multiply each term by the LCM of 4 and 6, which is 12:-
15x -36 = 2y..................(1)
and second multiply by 5:-
2x + y = 9..............(2)
solving:-
from equation (2) y = 9-2x, substitute in equation (1):-
15x - 36 = 2(9-2x) = 18 - 4x
19x = 54
x = 54/19 = 2.84
so y = 9 - 2(2.84) = 3.32
The one that is like this:^
The number must be 0, because any other number would multiply to a different product.
