Ответ:
x = -16; correct option is C
Step-by-step explanation:
From the question, 2(3 + x) = 5x + 54
First open the bracket
6 + 2x = 5x +54
Combine like terms
6 - 54 = 5x - 2x
-48 = 3x
Divide both sides by 3
x = -48/3
x = -16
Ответ:
So he came home with $20
£14.50+ £8.20= $22.70
Then 80-22.7= 57.30
57.30-22.70=34.6
So if he came home with $20 we do 34.60-20=$14.6
So his lunch was $14.6
Hope this helped and sorry if it’s wrong
