Can someone by solving the following system of equations? it’s on the photo

Step-by-step explanation:

7x - 8y = 15(1)

-6y - 5y = -1(2)

Multiple (1)×5 & (2)×8

35x - 40y = 75(3)

-48x - 40y = -8(4)

Substracting (4) from (3)

35x +48x = 75 + 8

83x = 83

x = 83/83

x = 1

Putting x = 1 in (1)

7(1) - 8y = 15

7 - 8y = 15

-8y = 15 - 7

-8y = 8

y = -8/8

y = -1

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
