12 ÷ (0.5x-4) = 6 solutions
Multiply both sides by (0.5x-4) to get 12 = 6 (0.5x-4), that is, 12 = 3x-24
Add 24 to both sides to get 36 = 3x, and divide by 3
The solution is x = 12
o(∩_ I hope I can help you!
4 * (x + 0.5x) = 28
4*(x+0.5x)=28
4x+2x=28
6x=28
x=28/6
x=14/3
x-2/5x-20x=28
The original equation can be reduced to (1-2 / 5-20) x = 28, that is, x = 140 / 97
8x12-5x = 18,12 (x-0.36) = 26.4 solve the equation and test it
The solution 96-5x = 185x = 96-185x = 78x = 15.6 test: left = 8 × 12-5 × 15.6 = 96-78 = 18 = right ﹣ x = 15.6 is the solution of the equation, 12x-4.32 = 26.412x = 26.4 + 4.3212x = 30.72x = 2,56 experience: left = 12 × (2.56-0.36) = 12 × 2.2 = 26.4 = right ﹣ x = 2.56 is the solution of the equation
