Question

3x+1/5=2-x solve the equation and check it​

Answer 1

• Solving

3x + 1/5 = 2 - x

3x + x = 2 - 1/5

4x = ( 10 - 1 ) / 5

4x = 9/5

x = 9 / 5 x 4

x = 9/20

• Checking

3 x 9/20 + 1/5 = 2 - 9/20

27/20 + 1/5 = 2 - 9/20

LCM = 20

( 27 + 1 x 4 ) / 20 = ( 2 x 20 - 9 ) / 20

( 27 + 4 ) / 20 = ( 40 - 9 ) / 20

31/20 = 31/20

Hence checked .
