Question

find x and solve the equation​

Answer 1

Answer:

$\frac{2x + 3}{3} = \frac{7x + 45}{15}$

$15(2x + 3) = 3(7x + 45)$

$30x + 45 = 21x + 135$

$30x - 21x = 135 - 45$

$9x = 90$

$x = 10$

by substitute the value of x in the equation can solve equation by equation both answers

Hi mate...✨

Greetings to u !!

Q. Solve - $\frac{2x}{3} +1=\frac{7x}{15} +3$

Ans:

$\frac{2x}{3} +1 = \frac{7x}{15} +3\\\\\frac{2x+3}{3}=\frac{7x+3*15}{15} \\\\\frac{2x+3}{3}=\frac{7x+45}{15}\\\\15(2x+3)=3(7x+45)\\\\30x+45=21x+135\\\\30x-21x=135-45\\\\9x=90\\\\x=\frac{90}{9}\\\\x = 10$

⇒ x = 10

• Firstly, we multiplied the other term of numerator with denominator in both the sides as to gain a common denominator.

• Then, we cross-multiplied both the sides with denominators of opposite side by transposing.

• Then, we transposed the like terms to one side and with further basic operations we got the value of x as 10.

∴By solving the equation, we got the value of x here as 10
