x = 2

Так, число 2 є коренем рівняння.

Answer 2

Solution to the Equation 3x + 8 = 7x

To determine if the number 2 is a root of the equation 3x + 8 = 7x, we can substitute x = 2 into the equation and check if the left-hand side equals the right-hand side.

Substituting x = 2 into the equation: 3(2) + 8 = 7(2)

Solving the equation: 3*2 + 8 = 7*2 6 + 8 = 14 14 = 14

The left-hand side of the equation equals the right-hand side when x = 2. Therefore, 2 is a root of the equation 3x + 8 = 7x.
