Question

find the value of x a)3+x/4=5 b) x/2 - x/3 = 4 c) a x+b = 0 where a. b are any integers d) 50/x + 4 =14​

Answer 1

Answer:

(a) x = 8

(b) x = 24

(c) x = -2 and

(d ) x = 5.

Explanation:

According to the question, we need to find out the value of x.

• For $3 + \frac{x}{4}$ = 5

⇒$\frac{12 +x}{4}$ = 5

⇒ 20 = 12 + x

⇒x = 20 - 12 = 8

• For $\frac{x}{2} - \frac{x}{3}$  = 4

⇒$\frac{3x - 2x}{6}$ = 4

⇒3x - 2x = 24

⇒ x = 24

• For ax + b = 0

According to the question a and b are any integers.

• An integer is a whole number that can be positive, negative, or zero and is not a fraction.

So, let x = 1 and b = 2

⇒1 . x +  2 = 0

⇒x = -2.

• For $\frac{50}{x}$ + 4 = 14

⇒$\frac{50 + 4x }{x}$ = 14

⇒ 50  + 4x = 14x

⇒50 = 10x

⇒ x = $\frac{50}{10}$ = 5.

Final answer:

Hence, the value of x ;

(a) x = 8 , (b) x = 24 , (c) x = -2 and (d ) x = 5.
