The elimination method is ideal for solving this system of equations. By which number must you multiply the second equation to eliminate the "yvariable, and what is the solution for this system?
x+3y= 42
2x - y= 14
O A. Multiply the second equation by-3. The solution is x= 12, y = 9.
OB. Multiply the second equation by -2. The solution is x= 12, y= 10.
OC. Multiply the second equation by 2. The solution is x= 15, y = 9.
OD. Multiply the second equation by 3. The solution is x= 12. y = 10.

x=half

step-by-step explanation:

there are infinitely many solutions.

step-by-step explanation:

a child is 12 years old, and his father is 32 years older. in how many years will the age of the father be 2 times the age of the child?

******************

this needs to be the answer format, or else your answer is incomplete.

if the number of years is x, then the equation is

in __ years

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
