Answer: is the same as 12 + 50
Step-by-step explanation:
Here we want to solve the equation 13 + 49 = 12 + x
for the number X.
An easier way to see it is that in the right eqation we subtracted 1 to the number in the left, so if we want to keep the equality we need to add 1 to the other number, so the answer would be x = 50, now let's solve it using math.
13 + 49 = 12 + x
we need to isolate x in one side of the equation, so we subtract 12 in both sides, this is:
13 + 49 - 12 = 12 + x - 12 = x
13 - 12 + 49 = x
1 + 49 = x
50 = x
