Question

please. fast.
give me answer​

Answer 1

Answer:

(i) 1

(ii) (-9)

(iii) 9

Step-by-step explanation:

$(i)\ (3x+5)-2(x-5)=4(x+3)\\=>3x+5-2x+10=4x+12\\=>x+15=4x+12\\=>x-4x=12-15\\=>-3x=-3\\=>x=-3/-3=1$

$(ii)\ 2a+3-4(a+3)=9\\=>2a+3-4a-12=9\\=>-2a-9=9\\=>-2a=9+9\\=>-2a=18\\=>a=18/(-2)=(-9)$

$(iii)\ \frac{4a-1}{7} = \frac{3a+3}{6} \\=>6(4a-1)=7(3a+3)\\=>24a-6=21a+21\\=>24a-21a=21+6\\=>3a=27\\=>a= 27/3 = 9$

Thanks!!
