1.solve the equation by transposition.Check the answer -2/3+a=1/5

2.Solve 7x=13=4x+43 3.Solve the equation and check your answer 1/5u= -3/5 4.After 15 years,Salma will be four times as old as she is now.Determine her age. Plz solve these sums and send the answer my dear guys.At least solve the sums u know and send the answers.Hope u guys help me!

4)Let salma's present age be 'x'. So forming an equation, x+ 15 = 4x Transposing 'x' to RHS 15=4x-x 15=3x Transposing 3 to LHS. 15/3=x 5=x Therefore, x=5

4) Let Salma`s present age be `x` years After 15 years her age will be x +15 years 4 times her age = 4x According to the question ⇒4x = x+15 ⇒4x-x = 15 ⇒3x = 15 ⇒x = 15/3 ∴x = 5 ∴Her present age = 5 years.
