Multiply each side by x to get rid of the fraction
2x + 5 = 7x
Subtract 2x from each side to get the x's on one side
5 = 5x
Divide by 5 to get x alone
1 = x
Plug 1 back in for x to see if it works out
2 + 5/1 = 7
2 + 5 = 7
7 = 7
Hope this helps

Subtract 2 from both sides to remove the 2 on the left.
5/x = 5
To remove the x on the left, multiply both sides with x.
5 = 5x
Divide both sides with 5 to obtain the value for x.
5x = 5
x = 1
