8(4x+5)=136
Multiply the number outside of the parenthesis(8) with the numbers inside the parenthesis(4x and 5).
32x+40=136
Subtract 40 from both sides
32x=96
Divide both sides by 32 so the only thing remaining on the side of the variable is only the variable itself.
Final Answer: x= 3
To get the decimal think of 3/8 as a division question -3 divided by 8
3/8=0.375
now times the decimal by 100
0.375 * 100=37.5
so the answer is going to be 37.5%
