Solve a linear equation in the form a x + b = c. Use a negative value for b when the equation contains subtraction.
Solutionx = 4
Standard form2x + 3 = 11
Show the steps
1. Start with the equation
2x + 3 = 11
2. Move the constant term
Subtract 3 from both sides: 2x = 11 - 3 = 8.
3. Divide by the coefficient of x
x = 8 / 2 = 4.
