Answer:
multiply by denominator to start...
a) 3x-10= 8
3x = 18
x = 6
b) x-3 + 5 = -10
x-3 = -15
x = -12

Answer:
Step-by-step explanation:
[tex]a) \dfrac{3x}{2}-5=4[/tex]
Add 5 to both sides
[tex]\dfrac{3x}{2}-5 +5 = 4 + 5\\\\\dfrac{3x}{2} = 9 \\\\Now \ multiply \ both \ sides \ by \ 2 \\\\\dfrac{3x}{2}*2 = 9*2\\\\3x = 18\\Now \ divide \ both \ sides \ by \ 3\\\\x =\dfrac{18}{3}\\\\[/tex]
x = 6
[tex]b) \dfrac{x-3}{5} + 1 = -2\\\\\\Subtract \ 1 \ from \ both \ sides\\\\\dfrac{x-3}{5} = -2 -1\\\\\dfrac{x-3}{5} = -3\\\\Multiply \ both \ side \ by \ 5\\\\x - 3 = -3*5\\\\x -3 = -15\\\\[/tex]
Add 3 to both sides
x = -15 +3
x = -12
