which of the following 4 questions has the solution of the lowest value

A: x-7=28
B: x+19=-5
C:x-6=-16
D: x+25=2

1 answer

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

A: x - 7 = 28
Adding 7 to both sides:
x - 7 + 7 = 28 + 7
x = 35

B: x + 19 = -5
Subtracting 19 from both sides:
x + 19 - 19 = -5 - 19
x = -24

C: x - 6 = -16
Adding 6 to both sides:
x - 6 + 6 = -16 + 6
x = -10

D: x + 25 = 2
Subtracting 25 from both sides:
x + 25 - 25 = 2 - 25
x = -23

Out of these equations, the lowest value is -24, the solution to equation B: x + 19 = -5.
