Question

Q -3 Solve the following equations. (1) y-4=7 (2)x - 5 = 0. (3) 3 (n - 2 )=48​

Answer 1

Step-by-step explanation:

(1) y-4=7

y=7+4

y=11

(2) x-5=0

x=5

(3). 3(n-2)=48

3n-6=48

3n=48+6

3n=54

n=54/3

n=18

Answer 2

Answer:

1. y = 11

2. x = 5

3. n = 18 ( Explained in diagram that how 3 ( n - 2 ) = 48 = 3n - 6 = 48 )

Step-by-step explanation:

1. y - 4 = 7

y = 7 + 4 = 11

2. x - 5 = 0

x = 0 + 5 = 5

3. 3 ( n - 2 ) = 48

3n - 6 = 48

3n = 48 + 6

3n = 54

$\sf n = \frac{54}{3} = 18$
