i need help in this problem it's algebra problem

133=-7(1-4k)

Step by Step solution:

Step 1:multiply by 1/-7 the whole equation

(1/-7)[133] = (1/-7)[-7(1-4k)] ==> 133/-7 = (1-4k) ==> -19 = (1-4k)

Step 2: add -1 the whole equation

-19-1 = -1+1 -4k ==> -20= -4k

Step 3: multiply by (1/-4) the whole equation

(1/-4)(-20)= (1/-4)(-4k) -20/-4=(-4/-4)k

5=k o k=5
