Solve the equation 5.3g+9=2.3g+15 find the value of g

Answer 1

Start by "moving" the g terms to one side of the equation by subtracting 2.3g from both sodes of the equation:

5.3g - 2.3g + 9 = 2.3g + 15 - 2.3g

Then:

3g + 9 = 15

Subtract 9 from both sides of the equation:

3g + 9 - 9 = 15 -9

3g = 6

Divide both sides of the equation by 3:

3g/3 = 6/3

AND g = 2

You can verify this solution by substituting 2 for g:

5.3 *2 + 9 = 2.3 * 2 + 15

10.6 + 9 = 4.6 + 15

19.6 = 19.6
