The solution the system x = -4y + 4; 2x + 8y = 8 has is: C. infinitely many solutions.

x = -4y + 4 (equation 1), can be rewritten as x + 4y = 4

2x + 8y = 8 (equation 2), devided by 2 on both sides: x + 4y = 4

Therefore, equation 1 and 2 are the same line, and there are infinite solutions to the line system.

x = -4y + 4 (equation 1), can be rewritten as x + 4y = 4

3x – 4y = 9

–3x + 2y = 9

Adding the above equations: -2y = 18, y = 18/-2 = -9

3x – 4(-9) = 9

3x + 36 = 9

3x = 9 - 36 = - 27

x = -27/3 = -9

The solution for the sytem of equations 3x – 4y = 9; –3x + 2y = 9 is D. (–9, –9)

–3x + 2y = 9

Adding the above equations: -2y = 18, y = 18/-2 = -9

3x – 4(-9) = 9

3x + 36 = 9

3x = 9 - 36 = - 27

x = -27/3 = -9

The solution for the sytem of equations 3x – 4y = 9; –3x + 2y = 9 is D. (–9, –9)

3x – 4y = –24 (equation 1)

x + y = –1 multiply 4 on both sides: 4x + 4y = -4 (equation 2)

Adding up equation 1 and equation 2 we get: 7x = - 28

so x = -28/7 = -4;

(-4) + y = –1,

y = - 1 + 4 = 3

The slotion for the system of equations 3x – 4y = –24; x + y = –1 is B. (–4, 3)

x + y = –1 multiply 4 on both sides: 4x + 4y = -4 (equation 2)

Adding up equation 1 and equation 2 we get: 7x = - 28

so x = -28/7 = -4;

(-4) + y = –1,

y = - 1 + 4 = 3

The solution of the system y = x + 5; y = –5x – 1 is (-1, 4)

y = x + 5

y = –5x – 1

Replace y in the second equation with the first one;

x + 5 = –5x – 1

x + 5x = - 1 - 5

6x = -6

x = -1

y = -1 + 5 = 4

y = x + 5

y = –5x – 1

Replace y in the second equation with the first one;

x + 5 = –5x – 1

x + 5x = - 1 - 5

6x = -6
