which equation has the solution of the lowest value?

x-10=20
x+18=-3
x+7=25
x-12+=-1

To find the solution with the lowest value, we would solve each equation and compare the values of x.

1) x - 10 = 20
Adding 10 to both sides: x = 30

2) x + 18 = -3
Subtracting 18 from both sides: x = -21

3) x + 7 = 25
Subtracting 7 from both sides: x = 18

4) x - 12 + (-1) (Simplifying the equation)
x - 12 - 1 (Combining like terms)
x - 13 (The simplified equation)

The solution with the lowest value is x = -21 from equation 2).

you surre

I apologize for the mistake in my response. Let's correct it:

1) x - 10 = 20
Adding 10 to both sides: x = 30

2) x + 18 = -3
Subtracting 18 from both sides: x = -21

3) x + 7 = 25
Subtracting 7 from both sides: x = 18

4) x - 12 + (-1) = 0 (Adding 1 to both sides)
x - 12 = 1 (Adding 12 to both sides)
x = 13

The solution with the lowest value is x = -21 from equation 2).
