Solve the equation, x + 1 = x/2 + 4

The answer should always end with x = …, so we need to rearrange and simplify the equation to solve this.First write out the full equation: x + 1 = x/2 + 4Multiply everything by 2 to remove the fraction: 2x + 2 = x + 8Substract by x, so that x is only on one side of the equation: x + 2 = 8Subtract by 2, so that all numbers are on the right: x = 6
