1. (-4 , 3) : substitute way .
2. (10 , -1) : elimination way.
3. (26/7 , -26/7 ) : elimination way.
4. ( 1 , 1) : elimination way.
Step-by-step explanation:
first do and there come some answer and take them eqn (i) and in 2nd put first eqn value and there will answer come
Let x be the number of new laptops and y be the number of tablets that
the company should buy. The equations that best show the given
conditions are as follows,
x + y = 30
515x + 285y = 11080
Solving simultaneously for the values of x and y gives an answer of x = 11 and y = 19.
Thus, the business should buy 11 laptops and 19 tablets.
I’m sorry. But none of your choices are correct. The correct answer would be 3 and 4. Further more explaining= 3+ 2 times 4 is 24. 2x= 4. That equals 8 and 3 times 8 is 24
