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 is a if I am not mistaken
Answer:
100%
Step-by-step explanation:
Since 56/56 employees at the sports shop work part time, that means 100% of them do, or all of them.

Hello from MrBillDoesMath!
Answer: -3 and 2
Discussion:
The equation to solve is:
6/m + 2 = (m+3)/(m-1)
Multiple both sides by m * (m-1).
6/m * (m*(m-1)) + 2 m (m-1) = (m+3)/(m-1) * (m(m-1))
Simplify:
6 (m-1) + 2 m (m-1) = (m+3)*m =>
6m -6 + 2m^2 - 2m = m^2 + 3m =>
2m^2 +4m - 6 = m^2 + 3m. Subtract m^2 and 3m from both sides
m^2 + m - 6 = 0. Factor this equation.
(m +3) ( m-2) = 0 so the solution set is -3 and 2
Thank you,
