Answer:

b = - 14

Step-by-step explanation:

Given

- \frac{5}{6}(8 + 5b) = 75 + \frac{5}{3} b

Multiply through by 6 ( the LCM of 6 and 3 ) to clear the fractions

- 5(8 + 5b) = 450 + 10b ← distribute left side

- 40 - 25b = 450 + 10b ( subtract 10b from both sides )

- 40 - 35b = 450 ( add 40 to both sides )

- 35b = 490 ( divide both sides by - 35 )

b = - 14

Solve for x. 8(9x-4)-2=3+2
gavmur [86]
So first you have to move the -2 over to the opposite side.
8(9x-4)=3+2+2
Then you can simplify the right side 
8(9x-4)=7
Then you distribute
8*9x=72x
8*-4=-32
so now you have...
72x-32=7
Then you move the 37 over
72x=39
Then you divide by 72 to isolate x
x=39/72 or x= 13/24 or <span>x=0.54167</span>
