twenty-six less than the product of nine and the difference of a number and one is four times the number.
what is that number?
:
Write what it says:
-26 + 9(x-1) = 4x
normally written
9(x-1) - 26 = 4x
9x - 9 - 26 = 4x
9x - 35 = 4x
9x - 4x = 35
5x = 35
x = 35%2F5
x = 7

Check it in the original equation
-26 + 9(7-1) = 4(7)
-26 + 54 = 28
