Question

8-2z+3(x+y), when x=4, y=9, Z=3

Answer 1

`8-2z+3(x+y)` when x is 4, y is 9, and z is 3

Substitute:

`8-2(3)+3(4+9)`

`8-6+39`

Solve:

`8-6+39\\=\fbox{23}`

Answer 2

`\huge\text{Hey there!}`

`\mathsf{8 - 2z + 3(x + y)}`

`\mathsf{= 8 - 2(3) + 3(4 + 9)}`

`\mathsf{= 8 - 6 + 3(4) + 3(9)}`

`\mathsf{= 8 - 6 + 12 + 27}`

`\mathsf{= 2 + 12 + 27}`

`\mathsf{= 14 + 27}`

`\mathsf{= 41}`

`\huge\text{Therefore, your answer should be:}`

`\huge\boxed{\mathsf{41}}\huge\checkmark`
