Solve the system by Elimination: 5x+4y=2 −5x−2y=4

Mathematics
2 answers:
Eddi Din [679]3 years ago

5x + 4y = 2
-5x - 2y = 4

So if we add both the equations 5x will be eliminated.

5x + 4y - 5x - 2y = 4 + 2
4y - 2y = 6
2y = 6
y = 3

As y is 3

x will be
5x + 4 x 3 = 2
5x + 12 = 2
5x = -10
x = -2

A gardener uses 1/3 of a liter of water to water 2/7 of a garden.
Serjik [45]

the gardener would need (1 + 1/6) liters of water to water the whole garden.

<h3>How much water would the gardener need to water the whole garden?</h3>

Here we know that the gardener needs 1/3 of a liter of water to water 2/7 of a garden.

Then we have the relation:

1/3 L = 2/7 of a garden.

Now, we want to get a "1 garden" in the right side of the equation, then we can multiply both sides by (7/2), so we get:

(7/2)*(1/3) L = (7/2)*(2/7) of a garden

(7/6)L = 1 garden.

(1 + 1/6) L = 1 garden

This means that the gardener would need (1 + 1/6) liters of water to water the whole garden.
