Step-by-step explanation:
1 kg = 2.2 pounds
0.45 kg = 1 pounds to see whether it's correct or not we can cross multiply the given equations
multiply 1 kg with 1 pounds and 0.45 kg with 2.2 pounds then check if they are equal
1 × 1 = 2.2 × 0.45
1 = 0.99 as you can see this is not an equality therefore the statement is wrong.
Substitution:
2x + (6(1/2x - 6)) = 19
2x + 3x - 36 = 19
5x - 36 = 19
+ 36
5x = 55
÷ 5
x = 11
y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5
Elimination:
y = 1/2x - 6
- y
0 = 1/2x - 6 - y
+ 6
1/2x - y = 6
3x - 6y = 36
2x + 6y = 19
(add)
5x = 55
÷ 5
x = 11
y = (1/2 × 11) - 6
y = 5.5 - 6
y = -0.5
I hope this helps! Let me know if you need me to explain why I did some things :)
