Answer:
(- 1, - 2 )
Step-by-step explanation:
Given the 2 equations
x - 3y = 5 → (1)
5x - 2y = - 1 → (2)
Rearrange (1) expressing x in terms of y by adding 3y to both sides
x = 5 + 3y → (3)
Substitute x = 5 + 3y in (2)
5(5 + 3y) - 2y = - 1 ← distribute left side
25 + 15y - 2y = - 1
25 + 13y = - 1 ( subtract 25 from both sides )
13y = - 26 ( divide both sides by 13 )
y = - 2
Substitute y = - 2 in (3) for corresponding value of x
x = 5 + (3 × - 2) = 5 - 6 = - 1
Solution is (- 1, - 2 )
Answer:70
Step-by-step explanation:910/13=70 so he gives away 70 loafs of bread.
Answer:
n + y
Step-by-step explanation:
a² - b² = (a +b)(a - b)
÷ 
{ (n + y) in the denominator and numerator will be cancelled ;
(n - y) in the denominator and numerator will be cancelled
= n + y
7/10 because you divide by 10
You divide 29:11= 2 7/11
so you have 2 full vans and one with 7 students.
so the answer is 7
