What is - 3 ?
Tyler has 4 boxes of apples. Each box has the same number of apples. After Tyler eats 3 apples, there are 109 apples left in the boxes. How many apples were in each box?
a - # of apples in each box
4a - 3 = 109
a = 28 There were 28 apples in each box.
The solution when you solve the equation
2(11 - 4x) = 38.
What is x = -2 ?
The solution when you solve the equation
-25 + 4(2x + 5) = -61.
What is x = - 7 ?
The solution when you solve the equation
16x - 19 = 113 - 6x.
