Solution equation: x + 1 / 6 x = 7
X + 1 / 6 x = 7
(1 + 1 / 6) x = 7
7x of 6 = 7
X = 7 / 6
x=6
1、 Solve the equation. 5x + 0.1X = 50 + 6.120
1、 Solve the equation
5x + 0.1X = 50 + 6.120 = 5x-3x 0.5x + 1.5x = 15.6 16x + 4-9x = 25
5.1 x = 56.1 x = 11 20 = 2x x = 10 2x = 15.6 x = 7.8 7x = 21 x = 3 parent
