Hence, there is 5 gallons of fuel Roselyn needed for her journey.
Answer:
Step-by-step explanation:

Multiply the equation by 4

5x - 2 + 2 = 2*(3y + 2)
5x +0 = 2*3y + 2*2
5x = 6y + 4
5x - 6y = 4 --------------------(I)

Multiply the equation by 6

2*(7y + 3) = 3x + 2*7
14y + 6 = 3x + 14
14y = 3x + 14 - 6
14y = 3x + 8
-3x + 14y = 8 ------------------------(II)
Multiply equation (I) by 3 and equation (II) by 5 and then add
(I)*3 15x - 18y = 12
(II)*5 <u>-15x + 70y = 40</u> {Now add}
52y = 52
y = 52/52
y = 1
Substitute y =1 in equation (I)
5x - 6*1 = 4
5x - 6 = 4
5x = 4 +6
5x = 10
x = 10/5
x = 2
Hey! :)
10y-3(y+5)
Distribute the -3.
-3*y= -3y -3*5= -15
10y-3y-15
7y-15
"A" is the answer.

<span>1. </span><span>Gaetano spent 37.80 dollars
including the tax for a pair of jeans
=> the tax is 8%, how much is the original cost of a pair of jeans?
=> 8% = 8/100
=> .08
Now, multiply .08 by 37.80 to get the 8% of 37.80
=> 37.80 x .08
=> 3.024 – this is the tax of a pair of jeans.
now, let’s subtract 3.024 by 37.80 to get the actual price of a pair of jeans.
=> 37.80 – 3.024
=> 34.776 – the original price of a pair of jeans without tax.
