Answer:

x = 7

y = -3

Step-by-step explanation:

the first equation is already solved for 'y' so we can substitute '-2x+11' for 'y' in second equation

3x + (-2x + 11) = 18

x + 11 = 18

x = 7

solve for 'y'

y = -2(7) + 11

y = -14 + 11

y = -3

The numeric value of the expression -a² - 2bc - |c| for a = -3, b = -5 and c = 2 is of 9.

<h3>How to find the numeric value of an expression?</h3>

The numeric value of an expression is found replacing each letter by it's attributed value.

In this problem, the expression is:

-a² - 2bc - |c|

The attributed values are:

a = -3, b = -5 and c = 2

Hence the numeric value will be given by:

-a² - 2bc - |c| = -(-3)² - 2(-5)(2) - |2| = -(9) + 20 - 2 = -9 + 18 = 9.
