Andrew knows that exactly two of the equations \(x(3+4)=4(x+3),\)\(4x+5=3(x+2),\)and \((x+2)+5(x-1)=3(x+3)\)
are true. What is the value of X
x(3 + 4) = 4(x + 3) 4x + 5 = 3(x + 2) (x + 2) + 5(x - 1) = 3(x + 3)
7x = 4x + 12 4x + 5 = 3x + 6 x + 2 + 5x - 5 = 3x + 9
7 - 4x =12 4x - 3x = 6 - 5 6x - 3 = 3x + 9
3x = 12 x = 1 6x - 3x = 9 + 3
x = 4 3x = 12
x = 4
