I have an equation:
2x + 3 = 11
is this correct?
x = 4?
Can you show me the workings
Yup
2x + 3 = 11
Subtract 3 from each side, and you get
2x = 8
Divide both sides by 2, and you get x = 4.

To solve the equation 2x + 3 = 11, you need to isolate the variable x on one side of the equation.
Start by subtracting 3 from both sides of the equation:
2x + 3 - 3 = 11 - 3
Simplifying the equation gives us:
2x = 8
Next, divide both sides of the equation by 2 to solve for x:
2x/2 = 8/2
Simplifying further yields:
x = 4
So, the correct value of x that satisfies the equation 2x + 3 = 11 is x = 4.
