Question

If 9x - 3 = 4, what does 9x - 2 = ?​

Answer 1

Answer: 5
Explanation: Solve for x

So separate x from other terms by adding 3 to 4

9x - 3 = 4
+3 +3
9x = 7

Then divide 9 from 7 to get the value of x

9x = 7
---- ----
9 9
x = 7/9

Now plug in the value of x for 9x - 2

9(7/9) - 2

Now solve

9(7/9) = 7

7 - 2 = 5
