Answer:
X=-5
Step-by-step explanation:
Since anything divided by one is still that number, then (x-7)/1 becomes x-7. So our equation now looks like:
(X-19)/2=(x-7).
Multiplying both sides by 2, we get
X-19=2x-14
Adding 19 to both sides:
X=2x+5
Subtract 2x from both sides:
-x=5
Multiplying both sides by -1, we get:
One person gets 3 10ths of it and the other gets 7 10ths
hello :
16t²+120 = y
16t² = y -120 so : t² = (y-120)/16
if : y-120 ≥ 0 t = ±√((y-120)/16)
2n+3n=5n = -41-9= 50
5n=50
n = 10
