WILL FAN AND MEDAL! Solve, using the substitution method. @ganeshie8 @amistre64 @Ashleyisakitty I am pretty sure it is either A or C

ganeshie8 (ganeshie8):

you're right its one of them

OpenStudy (anonymous):

Ok, would i just have to plug them in and multiply to find the right one?

ganeshie8 (ganeshie8):

to pin down further, simply plugin the point in one option into any of the equations..

OpenStudy (anonymous):

C?

ganeshie8 (ganeshie8):

take option A : plugin x = 12 into first equation

ganeshie8 (ganeshie8):

yes C is right, i hope you're not guessing

OpenStudy (anonymous):

No, I figured that 4x3 = 12 and then 2x-1/2 = 1 so 12-1 = 11
