Q. In the equation below, which number is represented by the box?\newline5×?+1=2×?+75\times ?+1=2\times ?+7\newline(A) 11\newline(B) 22\newline(C) 33\newline(D) 44
  1. Write Equation: First, let's write down the equation: 5×?+1=2×?+75\times ?+1=2\times ?+7.
  2. Rearrange Terms: Now, we need to get all the xx terms on one side and the numbers on the other side. So, we'll subtract 2×x2\times x from both sides: 5×x2×x+1=75\times x-2\times x+1=7.
