3x - 13 = 7(x + 2) - 4(x - 7)
3x - 13 = 7x + 14 - 4x + 28
3x - 13 = 3x + 42
3x = 3x + 55
0 = 55
0 ≠ 55
so…
answer: no solution
At first you may get confused but look at those numbers carefully :)
as you see first result is divisible buy one of the product (second product in all cases is unknown)
so let's check where it will lead us :)





Now you can clearly see that every number was multiplied by number 1 higher than itself.



etc...
it means that after equation sign there should be

because

:)
23.2 its already to the nearest tenth. After the decimal is the tenths............
Answer:
0
Step-by-step explanation:
(f-g)(x) = 12-sqrt(x)
plugging in 144, we get 12 - 12 = 0
one could also do f(x)-g(x) which would yield 24-24=0
