Hi,

we need to substitute 4 and 1 in the equation, so for every y, we replace it with a 1 and every X with 4 as X= 4, Y = 1

equation: X + X (X + Y) + Y

equation after substituting the numbers: 1 + 1 (1 + 4) + 1

Bidmas rules apply.

expand the bracket first. 1 (1 + 4)=

1 X 1= 1

1 X 4= 4

1 + 4 = 5

then the equation becomes: 1 + 5 + 1= 7

your answer is 7 if you want to evaluate it.

your answer is 1 + 1 (1 + 4) + 1 if you need the equation.

, hope that helps :)

\huge\text{Hey there!}


\huge\text{x + x(x + y) + y}


\huge\text{= 4 + 4(4 + 1) + 1}


\huge\text{= 4 + 4(5) + 1}


\huge\text{= 4 + 20 + 1}


\huge\text{= 24 + 1}


\huge\text{= 25}


\huge\boxed{\textsf{Therefore, your answer is: 25}}\huge\checkmark
