Answer: the answer is x=38
Step-by-step explanation:
X-18=20 we see that 18 is being SUBTRACTED from the x which means we have to do the opposite of subtraction is addition so 20+18=38
To check: you can plug 38 for x and subtract it from 18
Demonstration: 38-18=20
X = 38
Step-by-step explanation:
X-18 = 20
we move the constants (numbers) to one side and keep the variable, unknown on the other side
X= 20+18 (we change the sign whenever we move something to the opposite side)
x= 38
