Answer:
(5, - 2 )
Step-by-step explanation:
Given the 2 equations
9x + 5y = 35 → (1)
- 2x - 5y = 0 → (2)
Adding the 2 equations term by term will eliminate the y- term
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations for value of y
Substituting in (1) gives
9(5) + 5y = 35
45 + 5y = 35 ( subtract 45 from both sides )
5y = - 10 ( divide both sides by 5 )
y = - 2
Solution is (5, - 2 )
We can factorize the equation given:
<span>5 • 20 + 5 • 3
= 5(20 + 3)
= 5(23)
= 115</span>
