X/2 -5=20 please give details

vladimir1956 [14]

Answer: x=50

how?

$\frac{x}{2}$ - 5= 20 (first ADD 5 with 20 whatever you do on one side you have to do it to the other) so that gives us:

$\frac{x}{2}$ =25 (we see that 2 is being divided by x and we want X alone so the inverse of division is MULTIPLICATION)

25 x 2= 50

therefor the x=50

Bryan owns a pet store. He puts one parrot in per cage, he has one parrot extra. If he puts two parrots per cage, he has a cage

Ilya [14]

Answer:

4 parrots

3 cages

Step-by-step explanation:

Bryan has one more parrot than cages and one more cage than half the number of parrots. The following system of equations can be modeled for the number of parrots (P) and cages (C):

$P=C+1\\C-1=\frac{P}{2}$

Solving the linear system:

$P-1-1=\frac{P}{2}\\0.5P = 2\\P=4\\C=P-1=4-1=3$

Bryan has 4 parrots and 3 cages.
