Consider the system of equations. 2.+y=0
- 3x + 4y= 22
How do you solve the system of equations with Cramer's rule?
Drag a value or determinant expression into each box to correctly
solve the system using Cramer's rule.

See the attached image belowSolutions are x = -2 and y = 4

I've arranged the tiles into the correct positions, and wrote in the final result for each x and y.

The basic idea is to divide determinants as the vertical bars indicate (they aren't absolute value bars).

In each denominator is the determinant of the matrix which are the coefficients of the left hand side of each original equation given to you.

-------------

The numerators are a slight variation of this matrix. The x determinant will have you replace the first column with 0 & 22 getting which helps figure out the x solution. The y solution is similar as well, but we replace the y column instead of the x column. So that explains the

After you have the proper determinants set up, you just evaluate each determinant using the formula

and then simplify the results.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
