Question 447221
Pasha is thinking of a number such that when twice the number is added to three
 times one more than the number he gets the same result as when he multiplies four times one less than the number.
 What number is Pasha thinking about?
:
Let x = "a number"
:
2x + 3(x+1) = 4(x-1)
2x + 3x + 3 = 4x - 4
5x - 4x = -4 - 3
x = -7 is the number
;
:
See if that works
2(-7) + 3(-7+1) = 4(-7-1)
-14 + 3(-6) = 4(-8)
-14 - 18 = -32
