Answer 1

Explicación paso a paso:

a)

4(X–3) = 2X – 3

4X–12=2X–3

4X–2X=12–3

2X= 9

X = 9/2

B)

7/4X – 5 = 2(X–1) /×4

7X – 20 = 8(X–1)

7X – 20 = 8X – 8

7X – 8X = 20 – 8

–X = 12 /×-1

X = 12

C)

X–4/2 + 3 = 4X

X – 4 + 6 = 8X

X – 8X = –2

–7X = –2 /×-1

7X = 2

X = 2/7

D)

X/2 – 5X + 2 = – 1

X – 10X + 4 = – 2

–9X = –6 /×-1

9X = 6

X = 6/9 ==》 2/3
