Answer:
???
Step-by-step explanation:
Answer:
2x + 4 = 10 = x =3
Step-by-step explanation:
09 - 31 = 0 (the variable x is not present in the given system)
0 +5=6 (the variable x is not present in the given system)
2x + 4 = 10 = x = 3
09-1=4 (the variable x is not present in the given system)
51 - 7 = 1 (the variable x is not present in the given system)
3x + 1 = 9 = x = 8/3
I think 8. Plug in -4 for x. 1/2-4^2
Using pemdas -4^2 is 16 and 1/2•16 is 8. If there were parenthesis around 1/2x then 1/2•-4 would be -2 and -2^2 is 4 but since there aren’t parentheses then 8
