9∣9-8x∣ = 2x+3

Answers

Answer:

39/37 and 6/5

Step-by-step explanation:

To start, let's assume that 9-8x is positive (we will do this to get rid of the absolute value, but then check later). We get 9(9 - 8x) = 2x + 3, or 81 - 72x = 2x + 3, so 74x = 78 and x = 39/37. If we assume 9-8x is negative, the |9-8x| will turn into 8x-9, so we get 9(8x - 9) = 2x + 3, or 72x - 81 = 2x + 3 , so 70x = 84 and x = 6/5. If we plug the values back in, 9-8(39/37) needs to be positive, which works, and 9-8(6/5) needs to be negative, and this works, so the answers are 39/37 and 6/5.

Three times a number is the same as the difference of twice the number and seven. Find the number.

Answers

To solve this verbal equation, first we need to convert it into an written equation using integers and variables.

3n=2n-7

N is the variable for "the number".

We are trying to get the variable on one side of the equation to solve it.
So, we need to subtract 2n from both sides, which results in the equation

n= -7 

"The number" is -7.
