let x = "a number
:
Just write an equation for what it says:
"Four times the difference of a number and one is equal to six times the sum of the number and three."
4(x-1) = 6(x+3)
4x - 4 = 6x + 18
4x - 6x = 18 + 4
-2x = 22
x = 22%2F%28-2%29
x = -11
;
:
See if that's true!
4(-11-1) = 6(-11 + 3)
4(-12) = 6(-8), it is
