This is the correct answer to 4 1/2 meters. :)
You are asked to find the missing value in
... 40 + ? = 70
given that it is also the solution to
... ? + 5 = 35
Either way, you subtract the constant that is on the same side of the equation as the unknown.
... 40 + ? - 40 = 70 - 40
... ? = 30 . . . . the missing value
_____
You can check to see if this also satisfies the equation
... 30 + 5 = 35 . . . . . . . true
<span>−13b=9
divide both sides by -13
</span><span>−13b/-13 =9/-13
simplify
b = -9/13</span>
