Step-by-step explanation:
36 : x :: x : 16
16 x 36 = x2
576 = x2
Taking square root on both sides
24 = x
A is the answer :)
Since we are given z = 8, finding y is simple.
By replacing the z in y + z = 11, we can see that y = 3
After finding these two, x can be found
Answer:


Step-by-step explanation:
Since y=x+1 plug it into bottom equation as y.

Subtract 1 from both sides

Subtract 5x from both sides

Divide both sides by -4

Now x=-3 into the top equation to find y

y=-2
