If we have
y = 6x + 1 and x - y = 11, we can take advantage of y - y = 0 as follows:
Subtract x from both sides of the 2nd equation:
-y = 11 - x
Now combine
y = 6x + 1
-y = 11 - x
--------------
0 = 5x + 12. Solving for x, x = -12/5. Using the equation above, find y:
-y = 11 - x
= 11 - (-12/5)
= 55/5 + 12/5 = 67/5
Then the solution is (-12.5, 67/5).

Asked :
V = ...?
Answer :
V = ¼πd²h
= ¼ × 3.14 × 3² × 10
= ¼ × 3.14 × 9 × 10

X=30
Put in proportions x/45 = 18/27.
Cross multiply and get 27x= 45 x 18
Or 27X = 810.
Next, divide by 27 on both sides to get X=30.
Answer:
= -21 - 15g
Step-by-step explanation:
Given that:
= -3(7+5g)
By simplifying
As "-" sign will invert the inner signs:
= -21 - 15g
