Answer:
(6, - 3 )
Step-by-step explanation:
Given the 2 equations
2x + 5y = - 3 → (1)
2x + 2y = 6 → (2)
Subtracting (1) from (2) term by term will eliminate the x- term
(2x - 2x) + (2y - 5y) = 6 - (- 3), that is
- 3y = 9 ( divide both sides by - 3 )
y = - 3
Substitute y = - 3 in either of the 2 equations and solve for x
Substituting y = - 3 in (1)
2x + 5(- 3) = - 3
2x - 15 = - 3 ( add 15 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Solution is (6, - 3 )
Answer:
A I think this will help
Step-by-step explanation:
I just take the test 5 days ago
You need to remember that 100 pence = 1 pound sterling.
Halve both sides: 50 pence = 1/2 pound sterling
200 pence = <span>£2
</span>
50 pence 50 pence
Thus 50 p/ <span>£2 = ------------------ = ------------------ = 1/4
</span>£2 200 pence
50 p is 1/4 of <span>£2.</span>
