The solution equation: 5 / 12 of X-12 = 7 / 24, (2 / 11 + 1 / 2) - 2 / 11 of X-11 = 1 / 4
x=17/24 x=-1/4
How to solve the equation (52X + 24) / 35x = 11 / 7? The process is detailed
Cross multiply 7 * (52X + 24) = 11 * 35x, 364x + 168 = 385x, so x = 8
A number 0,7 less than the sum of 39 and 24 is the solution of the? Equation
One more question
Subtract a number from 19.5, and the result is 4.3?
Equation solution
Let this number be x, and the equation is countable
X+0.7=39+24
The solution is x = 62.3
Second question
Let this number be x, and the equation is countable
19.5-X=4.3
The solution is x = 15.2
One fifth of a number is 10 more than one sixth of it
Let this number be X
x/5-x/6=10
Multiply both sides by 30
6x-5x=300
x=300
That is: the number is 300
