So, let’s represent the number as n:
n+7=2n+3
Subtract both sides by 3:
n+4=2n
Now by n:
2n=4
Divide:
n=2
The number is 2

General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define</u>
a(c + b) = d
<u>Step 2: Solve for </u><em><u>c</u></em>
- Divide <em>a</em> on both sides: c + b = d/a
- Subtract <em>b</em> on both sides; c = d/a - b
M + 3= 9m -13
m -9m = -13-3
-8m =-16
8m=16
m = 16/8 = 2
