11 less implies: -11
two times a number (x) implies: 2x
equal to 27 implies: = 27
Set the equation together.
2x - 11 = 27 is your equation.
Solve for x. Note the equal sign. What you do to one side you do to the other. Add 11 to both sides
2x - 11 (+11) = 27 (+11)
2x = 38
Isolate the x. Divide 2 from both sides.
2x/2 = 38/2
x = 19
