Answer 1

Answer:

hope it helps you, mark me as brainliests!

Step-by-step explanation:

Answer (e)

2(x-2) + 3(4x-1)= 0

(2×x - 2×2) + (3×4x - 3× 1) = 0

2x - 4 +12x - 3 = 0

2x + 12x -4 -3 = 0

14x -7 = 0

14x = 0 + 7

14x = 7

x = 7 / 14

Answer (f)

5(2x-3) -3(3x-7)= 5

(5×2x -5×3) - (3×3x +3×7) = 5

10x -15 -9x +21 = 5

10x - 9x -15 +21 = 5

x +6 = 5

x = 5-6

x = -1
