What is the solution of the system? Use elimination. 2x + 2y +z = 7
-X – y +z = -5
x + 3y – 4z = 12

The solutions to the system of the equations by the elimination method will be:

Step-by-step explanation:

Given the system of the equations

solving the system of the equations by the elimination method

Rearranging the equations

solve for z:

solve   for y:

solve for x:

Therefore, the solutions to the system of the equations by the elimination method will be:

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
