Answer:
x=2/3
Step-by-step explanation:
25-(3x+5)=2(x+8)+x
25-3x-5=2x+16+x
20-3x=3x+16
20-3x-3x=16
20-6x=16
6x=20-16
6x=4
x=4/6
simplify
x=2/3
The answer would be x= 7,-7

Do the multiplication both sides,

Arrange the terms to LHS according to their variables,

Factorise this polynomial

So what we notice here is when you're multiplying two numbers you're getting 0 as answer.
So one of them must be 0.
If (x-1) is 0
then x = 1
similarly,
x-6=0
then, x= 6.
So the possible values of x are 1 and 6.
145 will work. It is an odd number and is greater than 142 and is less than 156
142 < 145 < 156
Other numbers such as 143, 147, 149,151,153, 155 will work.
