4x − 1 = −2 (x + 1) ⇒ Given
4x−1=−2x−2⇒ Distributive property (since we've multiplied out -2(x+1))
6x−1=−2 ⇒ <span>Addition or Subtraction Property of Equality (We've added 2x onto the 4x to get 6x)
</span>6x=−1 ⇒ <span>Commutative Property (We've moved -1 to the other side to get the sum -2+1 = -1)
</span>x=−¹/₆ ⇒ <span>Multiplication or Division Property of Equality (We divided both sides by 6)</span>
Of the 20 sandwiches prepared by Ali, Ben and Carla, Ali made a total of A) two sandwiches
Information of the problem:
- Total of sandwiches: 20
- Ali = x
- Ben = 3x
- Carla = 2*(3x)
To solve this problem we have to state the equation using the information of the problem:
Total of sandwiches = Ali + Ben + Carla
20 = x + 3x + 2*(3x)
20 = x + 3x + 6x
20 = 10x
x = 20 / 10
x = 2
Substituting the (x) value into the information of the problem we get:
Ali = 2 sandwiches
Ben = 3*2 = 6 sandwiches
Carla = 2*(3*2) = 2*6 = 12 sandwiches
