0.72=0.4(x+1.4)
0.72 = 0.4x + 0.56 (distribute 0.4 to x and 1.4)
0.72 - 0.56 = 0.4x (subtract 0.56 from both sides)
0.16 = 0.4x (subtract)
0.16/0.4 = x (divide both sides by 0.4)
0.4/0.4 * 0.16/0.4 = x (multiply by reciprocal to eliminate fraction)
0.4 * 0.16/0.4 = x (simplify)
0.16 = x (multiply)
x = 0.16
