Ugo [173]

Answer: root18


Step-by-step explanation:

A (2,2) x1=2 y1=2

B (5,5) x2=5 y2=5

Given the equation 9x+3/4 y=6 and 2x+1/2 y=9, by what factor would you multiply the second equation to eliminate y and solve the
anyanavicka [17]
To eliminate a cariable in a system of equations, we multiply the variable by a factor that will make both coefficients of the variable to be equal.
Thus, we multiply the coefficient of y in the second equation by a factor that will make it equal to the coefficient of y in the first equation. i.e. multiply 1/2 by a factor that makes it equal to 3/4. and the factor is 3/2.
Therefore, the third option is the correct answer.
