Answer 1

34

Explanation:

5 ( x + 2 ) + 9 ( y - 1 )

Solve the brackets.

5x + 10 + 9y - 9

Combine like terms.

5x + 9y + 1

Given that,

x = 3

y = 2

So, to find the value of the expression replace x and y with 3 & 2 and solve the expression.

Let us solve it now.

5x + 9y + 1

5 × 3 + 9 × 2 + 1

15 + 18 + 1
