Solve the system of equations using the substitution method. -5x − 3y = 16
y = x
(x, y) = (
,

Step-by-step explanation:

Now you can write the 1st equation like this.

Now simply Solve the 3rd equation

Now replace y as 2 in the 2nd equation like this

Now let's check whether the answer correct or wrong

Yes, the answer is correct

hope this helps you !!

$79500

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
