1.	4. Solve for 'x' and check the answer x/3+x/5+x/15=3
Answer» The right side: 2(x-2)-3(x-3)If we MULTIPLY the numbers with what’s in BRACKETS we WOUL get:2x-4–3x+9Now SIMPLIFY it: by adding numbers together and x(s) together:-x+5This outcome= the left hand side of the equ, so-x+5=5(x-5)Or,-x+5=5x-25Put the xs on oneside and numbers on the other:5+25=5x+x30=6xDivide both sides by 6 to get x30/6=6x/65=xSo,X=5
