Hi there!
Using the secret code that is used in math problems(:P), we derive the equation 3x+1=17-x.
3x+1=17-x
4x+1=16
4x=16
x=4

Answer:
<h2>128</h2>
Step-by-step explanation:
Step one:
given the expression w/8 - 4 = 20
the first operation is to isolate the term that has w by adding 4 to both sides
w/8 - 4+4 = 20+4
w/8 = 16
Required
the value of w
Step two:
the next step is to cross multiply
w=16*8
w=128
