Answer:
A) 4x+3y=14
B) 3x-2y=2
We multiply equation A) by (2/3)
A) (8/3) x +2y = 28/3 then we add this to equation B)
B) 3x-2y=2
5 (2/3) x = 11 (1/3)
x = 2
A) 4 * 2 + 3 y = 14
A) 3y = 6
y = 2
Step-by-step explanation:
1.7 meters are 17 decimeters
Total questions are 30.
70% of 30
=30(70/100)
=21
So, the questions can be wrong are 30-21.
