Show your work for the following problems: 1.)Solve by substitution:
3x - 3y = 33
2x + y = 19

2.)Solve by elimination:
-4x - 2y = -12
2x + 4y = -12

3.)Solve by elimination:
-6x + 6y = 6
-6x + 3y = -12

4.

Part 1 :

solve for y in 2x + y = 19:

y = 19 - 2x

substitute y = 19 - 2x into 3x - 3y = 33:

9x - 57 = 33

solve for x in 9x - 57 = 33:

x = 10

substitute x = 10 into y = 19 - 2x:

y = -1

Therefore,

x = 10

y = -1

Part 2 :

solve for x in -4x - 2y = -12:     x = 6 - y / 2

substitute x = 6 - y / 2 into 2x + 4y = -12:    6 + 3y = -12

solve for y in 6 + 3y = - 12:       y = -6

substitute y = -6 into x = 6 - y / 2:   x = 6

Therefore,

x = 6

y = -6

Part 3:

solve for x in -6x + 6y = 6:     x = y - 1

substitute x = y - 1 into -6x + 3y = -12:    -3y + 6 = -12

solve for y in -3y + 6 = -12:     y = 6

substitute y = 6 into x = y - 1:     x = 5

Therefore,

x = 5

y = 6

the answer above this is incorrect. btw, sorry if its late or anything, also can i get brainliest if you dont care?

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

35 is an outlier
