Question

Evaluate when x = -3 and y= -1:

Evaluate when x = 3, y = -3 and z = -2:

Which numerical expression is obtained by substituting x= 2, y= 6,
and z = 3 into the expression shown? x - (y+z)

Evaluate when x = 3, y = 2, and z = 4:

Answer 1

the answer is x=3, y=0, x=4 and, y=6

Answer 2

here is the answer: so if x = 3, y =2 and z = 4 then the answer is 3 - (2+4)
