Find the value of xx in the equation below.

4, point, 8, equals, 2, point, 1, plus, x
4.8=
2.1+x

1 answer

To solve the equation \( 4.8 = 2.1 + x \), we need to isolate \( x \).

  1. Start with the original equation: \[ 4.8 = 2.1 + x \]

  2. Subtract \( 2.1 \) from both sides of the equation: \[ 4.8 - 2.1 = x \]

  3. Now calculate \( 4.8 - 2.1 \): \[ 4.8 - 2.1 = 2.7 \]

Thus, the value of \( x \) is: \[ x = 2.7 \]

Therefore, \( xx = 2.7 \).
