Four times the difference of a number and 7 is 12. Find the number.
The question is based on a linear equation in one variable.
Answer: If four times the difference of a number and 7 is 12, then the number is 10.
Let's find the number which is the solution of the given equation: four times the difference of a number and 7 is 12.
Explanation:
Given that, four times the difference of a number and 7 is equal to 12.
Let the number be "a"
4(a - 7) = 12
4a - 28 = 12
4a = 28 + 12
4a = 40
a = 40/4
a = 10
Thus, 10 is the required number.
