As We need to find the value of x ,we need to have x alone at either LHS or R HS

• {2x+5x= 7x}

• Therefore 7x =70

• We need to have x alone in the LHS ,this is possible by dividing both sides of the entire equation by 7.since dividing by 7 in the entire equation will not make any change!

• Therefore 7x/7 = 70/7

• Therefore x = 70/7 =10

• The ans is x = 10 will satisfy the equation 2x + 5x = 70.

Answer 2

• 2x + 5x = 70
• taking x as common on LHS
• x( 2+5 ) = 70
• 7x = 70
• x = 70 / 7
• x= 10
