Question

The value of x for which 2 (x+5) = 3 (x+1)​

Answer 1

Answer:

Disadvantages of friction:

1.It always resists the motion, so extra energy is required to overcome it.

2.It causes wear and tear of machines.

3.It decreases the life expectancy of moving parts of vehicles.

4.Since friction is very useful in some cases while harmful in some cases, friction is called a necessary evil.

Answer 2

$\huge \bold{ \underline{ \underline \red{AnSwer}}} :$

$2(x + 5) = 3(x + 1) \\ \\ \implies 2x + 10 = 3x + 3 \\ \\ \implies 2x - 3x = 3 - 10 \\ \\ \implies \: \cancel{ -} x = \cancel{-} 7 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \implies \boxed{x = 7 }\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

so, value of x is 7
