Evaluate x + y + z for x = 2, y = -3, z = -4. 9 -9 -5 5

The answer to the expression is -5.

Substitute the values of all the variables into the expression.

x+y+z

2+(-3)+(-4)

-1+(-4)

-5

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
