solve each equation
x-7=13
14b=-56
-6=b18
To solve each equation, we will isolate the variable by performing the same operation to both sides of the equation.
1) x - 7 = 13
Add 7 to both sides:
x - 7 + 7 = 13 + 7
x = 20
The solution is x = 20.
2) 14b = -56
Divide both sides by 14:
14b/14 = -56/14
b = -4
The solution is b = -4.
Note: The third equation, "-6 = b18" appears to have a typo, as it is not a standard mathematical expression.
