Question

plz tell this answer I'm very confused its maths i want work explaining like what we write in exams​

Answer 1

Step-by-step explanation:

1.8x+4=3(x−1)+7

8x+4=3x+4

8x=3x

5x=0

x=0

LHS ⇒8x+4=8×0+4=4

RHS ⇒3(x−1)+7=3(0−1)+7=−3+7=4

LHS = RHS

Hence proved

I have this sum so here's the solution but dont forget to mark me as brainllist

Answer 2

Answer:

x=8/5

y=3/2

Step-by-step explanation:

8x-4=3(x-1) +7

8x-4=3x-3+7

8x-3x=7+4-3

5x=8

x=8/5

14y - 8= 13

14y = 13 + 8

y= 21/ 14

y= 3/2

Hope this helps you....
