To solve this we know that 2+7=9 so for 4+1(x)-x4 to equal 9 you would first multiply x and 4 to get 4x. Next you would subtract 1x-4x which equals -3x+4 . What you do to the right you do to the left so 9-4=5. Which you the have 5=(-3x) so you then divide the 3x by 3 which leaves you with x. So x = -5/3 .
