Question

plz solve sums for mee


​

Answer 1

5y-(3y-1)=y-7

5y-3y+1=y-7

2y+1-y+7=0

y+8=0

y= -8

Answer 2

Answer:

3t-2)(t+2)=8t^2-5

3t^2+6t-2t-4=8t^2-5

5t^2-4t-1=0

5t^2-5t+t-1=0

5t(t-1)+(t-1)=0

(t-1)(5t+1)=0

t-1=0,t=1

5t+1=0 , t=-1/5

x(2x+3)-2x(x-5)=6

2x^2+3x-2^x^2+10x=6

13x=6

x=6/13
