Step-by-step explanation:
This is awfully hard to read. Use returns to separate paragraphs.
ax = bx + 1 Subtract bx from both sides.
ax - bx = 1 take out x as a common factor
x(a - b) = 1 Divide both sides by a - b

Answer: 52.38%
Step-by-step explanation:
11 out of 21
11/21
.5238
52.38%
1.44 per kg
take 1.3 x 2, then subtract 12.7, finally divide that by 7
x+y=23
x-y=5
First, add the equations.
2x=28
x=14
Then...
14+y=23
y=9
Therefore the answer is...
x=14 y=9
