Answer:
5
Step-by-step explanation:
3(2x-5)-2=x+8
6x-15-2=x+8
6x-17=x+8
6x-x-17=8
5x-17=8
5x=8+17
5x=25
x=25/5
x=5
(3x − 5) − (4x + 6)
Pretend that there is a 1 in front of the first bracket.
Pretend that there is a -1 in front of the second bracket.
Multiply the first bracket by 1
(1)(3x)=3x, (1)(-5)=-5
Multiply the second bracket by -1
(-1)(4)=-4, (-1)(6)=-6
3x-5-4x-6
3x-4x-5-6 ( combine like terms)
-x-11
Answer: -x-11 or -11-x
