Answer:
x = 8/11
Step-by-step explanation:
5x - 4 = -6x + 4
Collect like terms
5x + 6x = 4 + 4
11x = 8
x = 8/11

28 is 4 times 7, so we will rewrite it like that.

7 is 7 times 7, so we will rewrite it like that.

So the simplest form is,
Answer: 1
Step-by-step explanation:
6+4×5-5²
=6+20-25
=1
2) (9x² - 18x - 7) / (3x + 1)
