Question

Which of the following four equations has the solution of the lowest value?

x - 6 = - 16

x - 7 = 28

x + 19 = - 5

x + 25 = 2

Answer 1

To find the solution of each equation, we will isolate the variable x.

1) x - 6 = - 16
Adding 6 to both sides of the equation:
x = - 10

2) x - 7 = 28
Adding 7 to both sides of the equation:
x = 35

3) x + 19 = - 5
Subtracting 19 from both sides of the equation:
x = - 24

4) x + 25 = 2
Subtracting 25 from both sides of the equation:
x = - 23

We can see that the equation with the lowest solution value is x = -24, so the equation "x + 19 = - 5" has the lowest value.
