im assuming your equation is 2x + 1 = 7 in this case you need to find what x equals
2x + 1 = 7
2x + 1 - 1 = 7-1
2x = 6
x = 3
put it back into the equation to check if your answer is correct
2(3) + 1 = 7
6 + 1 = 7
7 = 7 Correct!
if your equation is 2x - 1 = 7
x = 4
check it
2(4) - 1 = 7
8 - 1 = 7
7 = 7 Correct!
if your equation is 2x1 = 7
x = 7/2
check it
2(7/2)1 = 7
2(7/2) = 7
2 * 7 / 2 = 7
14/2 = 7
7 = 7 Correct!
hope i got your equation right. if not you can message me on my message board to get more help.
