4r + 4 = 5r
4r - r = 3r
4r x r = 4r^2
4r/r = 4

In algebra, when you see an expression like "4r r," it means 4 times r times r, which simplifies to 4r^2. This is because when you multiply like terms with the same base (r in this case), you add the exponents. So, r * r = r^2. Therefore, 4r r simplifies to 4r^2.
Since 4R and R both contain a like term (R), you can combine them: 5R would be 4R plus R simplified
4r +3 = 3r-2 r + 3=-2 r=-5 basically collect terms so that you get one coefficient of r (in this case 4r on one side and 3r on the other. To get the three r over to the other side you subtract 3r on both sides.) Then r+ 3=-2, so that's simple algebraic manipulation.
-4r = 8Divide each side of the equation by -4 :r = -2
-2=4r+s s=-4r-2 or s=-(4r+2)
To find the simplest form of the fraction p/q first find the highers common factor of p and q. If HCF(p, q) = 1 then the fraction is already in its simplest form and there is nothing to be done. Otherwise, divide p by the HCF to give r, divide q by HCF to give s and the simplest form is r/s.
