How do is 2x plus 8 equals x plus 10?

Answer 1

To solve the equation 2X+8=X+10 the first step is to get all instances of the variable 'X' on the same side of the 'equals' sign. To do this, we must first subtract 'X' from both sides of the equation:

2X+8-X=X+10-X which then becomes X+8=10. The next step is to leave the variable 'X' alone on it's side of the 'equals' by subtracting the numeral 8 from both sides of the equation:

X+8-8=10-8 which then becomes X=2.

To confirm that the solution is correct, we then substitute the solution we arrived at into the original equation in place of the variable 'X':

2*2+8=2+10

2*2=4 so:

4+8=2+10

4+8=12 and

2+10=12 so the final solution is:

12=12

Therefore the answer to the question "Is 2X+8 equal to X+10" is Yes, and the value of the variable 'X' is 2
