<span>"Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-2b' to each side of the equation.
4 + b + -2b = -5 + 2b + -2b
Combine like terms: b + -2b = -1b
4 + -1b = -5 + 2b + -2b
Combine like terms: 2b + -2b = 0
4 + -1b = -5 + 0
4 + -1b = -5
Add '-4' to each side of the equation.
4 + -4 + -1b = -5 + -4
Combine like terms: 4 + -4 = 0
0 + -1b = -5 + -4
-1b = -5 + -4
Combine like terms: -5 + -4 = -9
-1b = -9
Divide each side by '-1'.
b = 9
Simplifying
b = 9"- geteasysolution.com</span>
We know that 172 of them were wood, so the rest are metal. To find that number we do:
276 - 172 = 104 metal pins.
To find the percentage that they were metal, take the number of metal pins and divide by the total number of pins:
104/276 is about 0.3768.
Multiply this by 100:
37.68
So, the percent of metal pins is 37.68%.
