Adding the fractions on the RHS of the equation in the usual way gives
A/(2-x) + B/(1+3x) = (A(1+3X) +B(2-X))/((2-X)(1+3X)) = (5x +4)/((2-x)(1+3x))
This gives an expression for the origina...
To represent x = 0.0154 recurring as a fraction you need to eliminate the recurring element. You do this by finding the nearest multiple of x with the same recurring decimal element. For example, multiply...
642/3 may seem difficult to calculate at first but really boils down to two simple steps. This is because 642/3 = (641...
x = 0.319319... As there are three numbers that are recurring, we multiply x by 1000. 1000x = 319.319319... Then we can remove the recurring part by subtracting x from 1000x. 999x = 319 x = 319/999. We no...
5x – 2 > 3x + 11
5x - 3x > 11 + 2
2x > 13
x > 13/2
x > 6.5
