Answer 1

Step-by-step explanation:

a.3x+8=5(x-2)

3x+8=5x-10

8+10=5x-3x

18=2x

2x=18

x=18/2

x=9.

b. x+5/2x-3=-1/2

2(x+5)= -1(2x-3)

2x+10= -2x+3

2x+2x=3-10

4x= -7

x= -7/4.

Plz follow me and mark me as brilliant.

Answer 2

Answer:

• $3x + 8 = 5(x - 2) \\ 3x + 8 = 5x - 10 \\ 3x - 5x = - 10 - 8 \\ - 2x = - 18 \\ x = 9$

• $\frac{x + 5}{2x - 3} = \frac{ - 1}{2} \\ 2(x + 5) = - 1(2x - 3) \\ 2x + 10 = - 2x + 3 \\ 2x + 2x = 3 - 10 \\ 4x = - 7 \\ x = \frac{ - 7}{4}$
