Answer:
-7 plus 19 equals 12.
Step-by-step explanation:
This can be done using the expression
-7 + x = 12.
-7 + x = 12
Add 7 to both sides.
x = 19.
Proof:
-7 + x = 12
-7 + 19 = 12
12 = 12
To find this you can do and equation:
-7+x= 12
To isolate the variable you must add -7 to each side and then you’ll get
x= 19
So your answer will be 19
-7+x= 12
To isolate the variable you must add -7 to each side and then you’ll get
x= 19
So your answer will be 19
