Question

HELP PLZZ I would really really appreciate it ​

Answer 1

Answer:

31

Method:

X + 21 = 52 is the same as 52 - 21 = x. 52 - 21 = 31 so x = 31

Answer 2

The equation is x + 21 = 52

In algebraic equations, you always want to isolate the variable (x) so To do that you would subtract 21 from both sides, and then you would do 52 - 21 = 32

x + 21 = 52
-21 = -21
x = 31
