Question

please find value of y​

Answer 1

Answer:

y = 52

Step-by-step explanation:

On Equating both the equalities,

3x + 7 = 4x - 12 +4

⇒ x = 15

Putting this value in the first equation, we get:

y = 3(15) +7

⇒ y = 45 + 7

⇒ y = 52

Answer 2

Answer:

Step-by-step explanation:

y= 3x+7

Put value in next equation

So

y =4(x-3)+4.......put value of y

3x+7 = 4x-12+4

3x-4x=4-12-7

-x = -15

So

X= 15...put in eq.1

So

Y= 3x+7

Y= 3*15+7

Y= 45+7= 52

So X =15 & y= 52
