Answer:
2
Step-by-step explanation:
The equation would be 5x - 3 = 7. "x" replaces "a number." First you would add 3 to both sides, simplifying to 5x = 10. Now, just divide 5 from both sides, getting the answer, x = 2. So, the number is 2. You can check your work by putting it back into the equation: 5(2) - 3 = 7 goes to 10 - 3 = 7 which goes to
7 = 7.
