Answer:
(5, - 4 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = - 2 → (1)
3x - y = 19 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the y- term
9x - 3y = 57 → (3)
Add (1) and (3) term by term to eliminate y
(2x + 9x) + (3y - 3y) = (- 2 + 57), that is
11x = 55 ( divide both sides by 5 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (1)
2(5) + 3y = - 2
10 + 3y = - 2 ( subtract 10 from both sides )
3y = - 12 ( divide both sides by 3 )
y = - 4
Solution is (5, - 4 )

Answer:
m=2-2
m=0
Step-by-step explanation:
U need to do substitution
So u carry both 2 from that side to cross the equal to sign. One becomes positive because it is carrying a negative sign at the other side
Answer:
I don't know the number of the ratio but i will create an example of 3 ways to write ratio
Let's use the number 10:8
you can write it like
- 10:8 (colon)
- 10 to 8
- 10/8 ( a fraction)
