To solve for b in the equation 20 + b = a, subtract 20 from both sides. The solution is b = a - 20.
Certainly! To solve for b in the equation 20+b=a, follow these steps:
Given the equation 20+b=a, where 'a' is a constant or a known value:
To isolate 'b', subtract 20 from both sides of the equation:20+b−20=a−20
This simplifies to:b=a−20
Therefore, the equation b=a−20 represents the solution for b in terms of 'a'. This equation indicates that 'b' is equal to the value of 'a' decreased by 20.
If there is a specific value for 'a', substitute that value into the equation b=a−20 to find the corresponding value of 'b'. Without a specific value for 'a', the solution remains in terms of 'a' reduced by 20.
