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.
