x = 4
Step-by-step explanation:
3 = 1 + x/2
collect like terms:
we need to make the variable stane alone. We do this by removing any number not attached to the variable x.
The number is +1, so we will subtract 1 from both sides of the equation
3 - 1 = 1 - 1 + x/2
2 = 0 + x/2
2 = x/2
The value of x = 4
