As you look at the picture above, you may notice that the WV is half of TV.
To solve for the equation above,
You need to learn first that the TV will be WV (2), because WV is only half of the TV, giving two WV.
After that, you have to write your equation.
Since we need two WV = (4x + 1) + (4x + 1) = 74(TV)
Simplify both WV, will give you = 8x + 2(WV) = 74(TV)
In order to get the x, subtract 2 from 74, finally giving you 8x=72
Divide 8 and 72, in order to obtain your x.
The answer is: X=9
