Sub k=-4 into first equation. 3*-4=-12. - 12-7=-19

-19

Step-by-step explanation:

first substitute K for - 4

3 (-4) - 7

then multiply 3 and - 4

3 times - 4=-12

Answer check

to check the answer u can just take the equation which is 3k-7 and the solution

3k-7=-19

and solve for K

3k=-12

divide 3 on both sides

K=-4
