Question

Simplify and solve the linear equations:-
a) 3(t-3) = 5(2t+1)
b) 15(y-4) – 2(y-9) + 5(y+6) =0
please tell before evening

Answer 1

Answer:

a) 3t-9=10t+5

-9-5=10t-3t

-14=7t

t=-2

Answer 2

Answer:

a)

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

3t-9=10t+5

3t-10t=5+9

-7t=14

t=14/-7

t= -2 answer

b)

15(y-4)-2(y-9)+5(y+6)=0

15y-60-2y-18+5y+30=0

18y= 60+18-30

18y= 48

y=48/18
