Question

if x\4=49\x then find of value​

Answer 1

Answer:

x/4 = 49/x

x² = 49 * 4

x= √49*4

x= 7*2

x= 14

Answer 2

The value of x= 14

GIVEN:

$\implies \: \frac{x}{4} = \frac{49}{x}$

TO FIND:

The value of x

SOLUTION:

$\implies \frac{x}{4} = \frac{49}{x } \\ \implies \: x \times x = 49 \times 4 \: (cross \: multiplication) \\ \implies \: x {}^{2} = 49 \times 4 \\ \implies \: x = \sqrt{49 \times 4} \\ \implies \: x = \sqrt{(7 \times 7) \times (2 \times 2)} \\ \implies \: x = \: 7 \times 2 \\ \implies \: x = \: 14$

NOTE:

• This type of questions can be solved by doing CROSS MULTIPLICATION.
• The standerd form of linear equation in one variable is ax+b=0
• Symbol of Implies should be given.
• In Cross Multiplication method the numerator one fraction is multiplied with the denominator of other fraction...
