Answer:
The algebraic expression for this would be 9 + 2x = 13
Explanation:
Step 1: Simplify both sides of the equation
2x + 9 = 13
Step 2: Subtract 9 from both sides.
2x + 9 - 9 = 13 - 9
2x = 4
Step 3: Divide both sides by 2.
2x/2 = 4/2
x = 2
Or, you can use a diffrent way (which I simply prefer).
Step 1: Subtract 9 from 13.
13 - 9 = 4
Step 2: Divide the number 4 by 2
4 รท 2 = 2
x = 2
Either way will get you the answer, hope this helps!
