Answer:
The equations whose solutions are -1/2 are:
1. 4x + 1 = 6x + 2
2. 3x + 7 = 5x + 8
Step-by-step explanation:
Using the digits 0 to 9 at most one time each, the equations whose solutions are -1/2 are:
1. 4x + 1 = 6x + 2
-2x = 1
x = -1/2
2. 3x + 7 = 5x + 8
-2x = 1
x = -1/2
Answer:
Yes
Step-by-step explanation:
xy=yx because either way, you would end with the same product. For example, if x was 3 and y was 2, you would have (3)(2)=(2)(3), giving you 6=6 which is, in fact, a true statement.

Answer:
3rd option
Step-by-step explanation:
(
)(x)
= ![\frac{f(x)}{g(x)}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28x%29%7D%7Bg%28x%29%7D)
=
← factorise numerator and denominator
=
← cancel (2x + 1) on numerator/ denominator
= ![\frac{x-3}{x+2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx-3%7D%7Bx%2B2%7D)
