Question

If x = −3 and y = −6, what is the value of 3x + 4y + 15?

A: 48
B: 35
C: −18
D: −48

Answer 1

Answer: -18 ==> C

Explanation:

x = −3 and y = −6

3x + 4y + 15=

3(-3) + 4(-6) + 15=

-9 + (-24) + 15 =

-9-24+15=

-(9+24)+15=

-33+15=

-(33-15)=-18 ==> C

Answer 2

c) -18

Explanation:

Given that,

→ x = -3

→ y = -6

Let's solve the problem,

→ 3x + 4y + 15

→ (3 × -3) + (4 × -6) + 15

→ -9 - 24 + 15 = -18

Thus, the solution is -18.
