Question

A certain number added twice to itself equals 4. What is the number?
Round and write your answer to the tenths place value. Do not include units​

Answer 1

i think it’s 1.3 because 1.3 + 1.3 +1.3= 4

Answer 2

x + x + x = 4
3x = 4
x = 3/4 or 0.75
rounded: 0.8

x is representing the number. 3x is the number added twice to itself. after that, you just divide each side by 3 to get 3/4
rounded, 0.8. the answer is 0.8
