138+(х+57)=218

Answer

To solve the equation \( 138 + (x + 57) = 218 \), follow these steps:

Simplify the left side: \[ 138 + x + 57 = 218 \] Combine \( 138 \) and \( 57 \): \[ 195 + x = 218 \]
Subtract \( 195 \) from both sides: \[ x = 218 - 195 \]
Calculate: \[ x = 23 \]

So, the solution is \( x = 23 \).

Question 2

138+(х+57)=218

Answer
