Question

What is the value of 3(y+4)-(x-1)when x=3 and y =2

Answer 1

16

Explanation:

Evaluate 3 (y + 4) - (x - 1) where x = 3 and y = 2:

3 (y + 4) - (x - 1) = 3 (2 + 4) - (3 - 1)

2 + 4 = 6:

3×6 - (3 - 1)

3 - 1 = 2:

3×6 - 2

3×6 = 18:

18 - 2

| 1 | 8

- | | 2

| 1 | 6:

Answer: 16

Answer 2

16

Explanation:

3(y+4)-(x-1)

Let x =3 and y =2

3(2+4) - (3-1)

PEMDAS says do parentheses first

3(6) -2

Then since there are no exponents, we multiply

18 -2

Finally we subtract

18-2
