Answer:

x = -1

y = -9

Step-by-step explanation:

<u>A</u><u>d</u><u>d</u><u> </u><u>each linear equation:</u>

Sum: 5x = -5

<u>Divide each side by </u><u>5</u><u>:</u>

Quotient: x = -1.

<u>Substitute x = </u><u>-</u><u>1</u><u> into the </u><u>first</u><u> equation:</u>

4(-1) - y = 5

<u>Solve</u><u>:</u>

-4 - y = 5

<u>Add 4 to both sides of the equation:</u>

-y = 9

y = -9.

<u>Check with the second equation:</u>

-1 + -9 = -10.

Correct.

4x-y=5
x+y=-10

Add the equations together which gets you

5x=-5

This would give you
x=-1

Then substitute the -1 in the equation x+y=-10

-1+y=-10

y=-9

The answer would be

(-1,-9)

There are 534 car parking spaces but 478 spaces are occupied,round to the nearest 10
suter [353]

Answer:

60

Step-by-step explanation:

If 478 out of 534 parking spaces are taken, then you will be <u>subtracting</u>. When you subtract 534 and 478 (534-478), then you get 54. Remember 5 and up round to 10. 4 and below round to 0. So 56 rounds to 60 because 6 is greater than 5.

Hope it helps!

Helen [10]
There are many factors, it is all a matter of preference, normally, you want to try to solve for the easiest one to get to
example

if y ou had

(x-3)^2+y=9
you would solve for y becuase it is less tricky

it is all a matter of preference
