We are asked to solve for a number such that:
Twice that number plus 4 equals 6
Which can be written in math terms as:
2 x + 4 = 6
Now we proceed to isolate the unknown in steps.
First we subtract 4 from both sides:
2 x + 4 - 4 = 6 + 4
we combine like terms:
2 x = 10
Now we divide both sides by 2 so as to cancel the factor 2 that accompanies "x":
2 x / 2 = 10/ 2
perform the indicated operations:
x = 5
