First step you should do is s<span>implify both sides of your equation: </span>29-(x+8)=6x-7 Distribute the Negative Sign: 29+-1(x+8)=6x-7 29+-1x+(-1)(8)=6x-7 29+-x+-8=6x-7 29+-x+-8=6x+-7 <span>Combine Like Terms: </span>(-x)+(29+-8)=6x-7 -x+21=6x-7 <span>Subtract 6x from both sides: </span>-x+21-6x=6x-7-6x -7x+21=-7 <span>Subtract 21 from both sides: </span>-7x+21-21=-7-21 -7x=-28 <span>Divide both sides by -7: </span>-7x/-7 = -28/-7 And now your answer should be: x=4 ~~~~~ Good luck~ Sans
B is the irrational. C & D are rational as they can be written in a ratio, aka a simple fraction. A is rational as it simplifies to +/-2, a whole number.
