Q. 6(y−4)=x−3y=CIn the system of equations, C is a constant. For which value of C is (x,y)=(−3,3) a solution?Choose 1 answer:(A) 3(B) 21(C) All real numbers(D) None of the above
Substitute y=C: Substitute y=C into the equation 6(y−4)=x−3. Since y=C, the equation becomes 6(C−4)=x−3.
Plug in values: Plug in the values x=−3 and y=3 from the solution point (−3,3) into the equation. This gives us 6(3−4)=−3−3.
Simplify left side: Simplify the left side: 6(−1)=−6. Now, the equation is −6=−6.
Check against original substitution: Since the equation −6=−6 holds true, the value of C that makes (x,y)=(−3,3) a solution must be checked against the original substitution. We substituted y=C, and since y=3 in the solution point, C must be 3.
