Question

Please help me find the value of x and show and explain work

Answer 1

2x + 3 = 9      Move all terms not containing x to the right side of the equation.

2x = 6             Divide each term by 2 and simplify.

x=3

Answer 2

You make 2x+3 equal 19 so like this 2x+3=19 then you subtract 3 over to 19 and that is 2x=16 then you divide 16 by 2 and that is 8 so x=8
