Answer:
solution is (- 3, 5 )
Step-by-step explanation:
given the 2 equations
6x - y = - 23 → (1)
8x + 3y = - 9 → (2)
rearrange (1) expressing y in terms of x
y = 6x + 23 → (3)
Substitute y = 6x + 23 into (2)
8x + 3(6x + 23 ) = - 9
8x + 18x + 69 = - 9
26x + 69 = - 9 ( subtract 69 from both sides )
26x = - 78 ( divide both sides by 26 )
x = - 3
substitute x = - 3 into (3)
y = (6 × - 3 ) + 23 = - 18 + 23 = 5
solution is (- 3, 5 )

Answer:
The cost of blouse after 25% discount is $103.5
Step-by-step explanation:
Cost of Blouse = $138
Sale = 25 %
New cost of Blouse will be:
25% of 138
= 25 / 100 * 138
= 34.5
So, New Cost of Blouse = Original Price - Discount Price
= 138 - 34.5
= $103.5
The cost of blouse after 25% discount is $103.5
Three more than twice the number is 25
The number you're looking for is 25. Simply work backwards.
25 - 3 (three more...) = 22
22 ÷ 2 (twice the number) = 11
