Solve the equation 120-156x = 40
solution
120-156x=40
-156x=40-120
x =-80÷-156
x =20/39
Solving the equation: 1-1 / 120 can be four is equal to (1-1 / 60 can be four) times 2
1-1/120x=2(1-1/60x)
1-1/120x=2-1/30x
1/30x-1/120x=1
1/40x=1
x=40
A number minus two has seven fifths, plus two and forty-four one equals one and seventy-two, find this number, set up equations, quick,
Let this number be x, then (is it 5 / 7?)
X-2 + 5 / 7 + 2 + 1 / 44 = 1 + 2 / 7
X = 1 and 2 / 7 + 2 and 5 / 7-2 and 1 / 44
X = 1 and 43 / 44
A number minus two has seven fifths, plus two and forty-four one equals one and seventy-two, find this number, set up equations, quick,
x-2(7/5)+2(1/44)=1(2/7)
x=9/7+17/5-89/44=(9*5*44+17*7*44-89*7*5)/(7*5*44)=4101/1540
