\(\frac{2x-x}{8}+5=35\)
2x-x=x
\(\frac{x}{8}+5=35\)
To get x by itself, multiply everything by 8.
\(x+40=280\)
Subtract 40 from both sides.
\(x+40-40=280-40\)
\(x=240\)
To verify, plug into the original equation.
\(\frac{2(240)-240}{8}+5=35\)
Simplify.
\(\frac{480-240}{8}+5=35\)
\(\frac{240}{8}+5=35\)
\(\frac{240}{8}=\frac{120}{4}=\frac{60}{2}=\frac{30}{1}\)
30/1=30
\(30+5=35\)
\(35=35\)
This is true, so x is 240.
I'm solving a slightly different problem than AT.......which interprtation is correct - who knows??
2x - x / 8 + 5 = 35 subtract 5 from both side
2x - x / 8 = 30 multiply through by 8
16x - x = 240
15x = 240 divide both sides by 15
x = 16
Thanks to AT.....for pointing out my silly error....!!!
Hey CPhill, on your third step where you multiply through by 8, the 2x wouldn't become 16x. It would stay x, as it would multiply by 8 then also divide by 8.
The way you did it, the answer doesn't work when plugged in.
2(2)-2/8 +5=35
4-2/8+5=35
2/8+5=35
1/4+5=35
21/4=35
This is not true, so x can not equal 2.
Do you see what I mean?
