Question

1.Factor: 3y(x – 3) -2(x – 3).2.Solve for x: 2x – y = (3/4)x + 6
​

Answer 1

1.Solution:

3y(x – 3) -2(x – 3).

= (x – 3)(3y – 2).

2.Solution:

2x – y = (3/4)x + 6.

or, 2x - (3/4)x = y + 6.

or, (8x -3x)/4 = y + 6.

or, 5x/4 = y + 6.

or, 5x = 4(y + 6).

or, 5x = 4y + 24.

or, x = (4y + 24)/5.

Therefore, x = 4(y + 6)/5
