The answer is: ____________________ x = 4y - 12 ; (Assuming the problem meant to solve for "x"; "in terms of "y"). _______________________ {Otherwise, the question might be "incomplete".}. ______________________________________________ The question seems incomplete; how can we solve for "x" when we do not know what "y" equals? __________________________ However, it could be possible to "solve for x" in terms of "y". To so this, we need to isolate ""x" on one side of the equation: _______________________________ Given: <span>y=1/4 (x) + 3 ; Let us multiply the ENTIRE EQUATION (both sides) by "4", to get rid of the "1/4" (fraction coefficent) of "x", and to "cancel out" the "1/4" fraction cofficient of "x" to the implied "1"; to help solve for "x" : ________________________________________ 4 *{ </span>y= 1/4 (x) + 3} ; ______________________ 4y = x + 12 ; Now we can subtract "12" from EACH SIDE of the equation; to isolate "x" on one side of the equation; and to solve for "x": _______________________ 4y - 12 = x + 12 - 12 ; ________________________ 4y - 12 = x ; This is our answer: ___________________________ x = 4y - 12 ; (Assuming the problem meant to solve for "x"; "in terms of "y").
