Answer 1

Answer:

$\frac{3}{4} (7x - 1) - (2x - \frac{1 - x}{2} ) = x + \frac{3}{2} \\ \\ \\ = \frac{84x - 12}{4} - \frac{4x - 1 - x}{2} = \frac{2x + 3}{2} \\ \\ = \frac{84x - 12 - 8x + 2 + 2x}{4} = \frac{2x + 3}{2} \\ \\ = \frac{ - 10 + 78x}{4} = \frac{2x + 3}{2} \\ \\ 2( - 10 + 78x) = 4(2x + 3) \\ \\ = - 20 + 156x = 8x + 12 \\ \\ = 156x - 8x = 12 + 20 \\ \\ = 148x = 32 \\ \\ x = \frac{32}{148} \\ \\ x = \frac{16}{74} \\ \\ x = \frac{8}{37}$

Answer 2

Step-by-step explanation:

3/4(7x-1)-[2x-(1-x)/2]=x+3/2

21x/4-3/4-2x+(1+x)/2=x+3/2

21x/4-2x+(1+x)/2-x=3/2+3/4

[42x-16x+4+4x-8x]/8=(12+6)/8

42x-16x+4+4x-8x=18

46x-24x=18-4

x =14/22

X=7/11

X=7:11
