Let's first solve the first equation:
(4×b-16)/2=102(4×b-16)=108×b-32=108×b=42b=5.25
Now, let's plug in the value of b into the second equation:
(2+5.25)/7×8=727.25/7×8=721.0357×8=728.2856=72
Therefore, the value of x is approximately 8.29.
Let's first solve the first equation:
(4×b-16)/2=10
2(4×b-16)=10
8×b-32=10
8×b=42
b=5.25
Now, let's plug in the value of b into the second equation:
(2+5.25)/7×8=72
7.25/7×8=72
1.0357×8=72
8.2856=72
Therefore, the value of x is approximately 8.29.
