Question

if x=-1,y=2 is a solution of the equation 3x4y= k, find the value of k​

Answer 1

$\huge\color{yellow}{\underline{\underline{answer\::}}}$

• 3x + 4y = k

• x = -1 and y = 2

• 3(-1) + 4(2) = k

• -3 + 8 = k

• 5 = k

So, k = 5

Answer 2

Answer:

k=5

Step-by-step explanation:

3x+4y=k

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

-3+8=k

5=k

k=5
