Question

3x /10+2x/5= 7x/25+42/25






​

Answer 1

Answer:

x = 4

Step-by-step explanation:

= 3x/10 + 2x/5 = 7x/25 + 42/25

= 3x+4x/10 = 7x+42/25

= 7x/10 = 7x+42/25

cross multiplication

= 7x(25) = 10(7x+42)

= 175x = 70x + 420

= 175x - 70x = 420

= 105x = 420

= x = 420/105

= x = 4 (ans)

Answer 2

Step-by-step explanation:

$\bold{3x/10+2x/5\:=\:7x/25+42/25 }$

$\bold{3x+4x/10\:=\:7x+42/25}$

$\bold{7x/10\:=\:7x+42/25}$

$\bold{7x/10\:=\:217/25}$

$\bold{7x\:=\:434/5}$

$\bold{x\:=\:12.4}$
