Question

a) 2X+1-7X+4= -2X+3X+27

b) 7X-5(X+6)=2X-8X-3

c) (X+4)+3(X-15= -2

d) 8-7(X-1)=(2X+5)-4

e) $\frac{1-X}{5}$

Answer 1

A)

2X+1-7X+4= -2X+3X+27

4X - 3 = X + 27

4X - X = 27 + 3

3X = 30

X = 30 : 3

X = 10

b)

7X-5(X+6)=2X-8X-3

7X - 5X - 30 = -6X - 3

2X - 30 = 6X - 3

2X + 6X = -3 + 30

8X = 27

X = 27/8

c)

(X+4)+3(X-15= -2

X + 4 + 3X - 45 = -2

4X - 44 = -2

4X = -2 + 44

X = 42/4= 11/2
