Solve using substitution
6x + 2y = 34
2x - 7y = -27

6x+2y=34

6x=34-2y

x=(34-2y)÷61st euation

2x-7y=-272nd equation

putting the value of x from equation 1st in equation 2nd we will get

2(34-2y)÷6-7y=-27

68-4y-42y=-27×6

-44y=-162-68

-44y=-230

y=230÷44

y=5.2

again putting the value of x in equation 1st

6x=34-2×5.2

x=23.6÷6

x=3.9

answer: sine

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
