Answer 1

-8

Explanation:

3x4= 12, 7+3=10x2=20

Answer 2

The value of the expression is -8

Explanation:

Numerical value of expressions

We are given the expression:

3x - 2(y + 3)

Let's find its value for x = 4 and y = 7.

Substituting both values into the expression:

3*4 - 2(7 + 3)

Operating:

12 - 2(10)

12-20

-8

The value of the expression is -8
