Algebra 2 questions help please....?

Question

need help solving 2 different problems:

#1) 2k - 1 = k - 5 + 3k

#2) 3x - 7(2x - 4) = 3(1 - 2x)

Need step by step help on solving this problem

Answer 1

1. 2k-1=k-5+3k

2k-1=4k-5

4=2k

2=k

2.3x-7(2x-4)=3(1-2x)

3x-14x+28=3-6x

-5x=-25

x=5

Answer 2

1) 2k - 1 = 4k - 5; subtract 4k

-2k - 1 = -5; add 1

-2k = -4

k = 2

2) 3x - 14x + 28 = 3 - 6x

-11x + 28 = 3 - 6x

-5x + 28 = 3

-5x = -25

x = 5
