Question

Algebraic expression 30 less than twice the sum of x and y

Answer 1

2(x+y)-30

First think of the sum of x and y that means we have to add x and y so x+y

Now twice the sum. 2(x+y) if we open the brackets we will get 2x+2y

Now 30 less than means subtraction

The equation formed is 2(x+y)-30
