Answer:
-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
add 7 on both sides
3k=-12
divide 3 on both sides
K=-4
Sub k=-4 into first equation. 3*-4=-12. -12-7=-19
