Me ayudan con esa ecuacion por sustitucion con la comprobacion pliss
1 answer:
<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5
1/5x+3y/2=2 => (1/5)x + (3/2)y = 2
Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:
2x + 15y = 20
</span><span>Multiply the 1st equation by -1:
-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.
Solution is (10,0).

No he actually got slower. if you divide 198\6 it equals 33 if you divide 248\8 you get 31
You can add any number like 42 plus 42 gives you 84
I think it's B not 100% about it tho
