How do I solve this equation ???
Anastaziya [24]

To solve for the variable b , we have to make it alone. The first thing we do is add 6.5 to both sides of the equation:

13.7b-6.5+6.5=-2.3b+8.3+6.5\\13.7b=-2.3b+14.8

Now add 2.3 to both sides:

13.7b+2.3b=-2.3b+14.8+2.3b\\16b=14.8

Finally, divide both sides by 16 to get the final answer:

\frac{16b}{16} =\frac{14.8}{16}

Therefore,

b=0.3

Hope this helps!

3x = 22 - 1 = 21
x = 21/3 = 7

Similarly,
AD = CD by symmetry
Therefore
4x = CD
4*7 = CD
28 = CD, the required line segment
