Answer 2

According to the information provided in the question.

It is stated in the preceding question that,

The presented information is the expression 3(x + 2) + 5x – 7​.

We need to find the value when x is equal to 2.

Here we have to simplify the expression we get,

$3(x+2)+5x-7\\3x+6+5x-7\\3x+5x+6-7\\8x-1$

When we add two number with sign (+) and (-) we do subtraction and given the sign of highest value.

Now substitute the value of x as 2 we get,

$8(2)-1\\16-1\\15$

Hence the value is 15.

The simplify expression is 8x-1
