Question

Write the first step you will use to separate the variable and then solve the equation.
1.3n+7=25
2.p-1=20
3.6m=96​

Answer 1

${\huge{\underline{\boxed{\mathbb{\purple{Answer::}}}}}}$

1) 3n+7 = 25

$\tt\implies$ 3n = 25-7

$\tt\implies$ 3n = 18

$\tt\implies$ n = 18/3

$\tt\implies$ n = 6

2) p-1 = 20

$\tt\implies$ p = 20+1

$\tt\implies$ p = 21

3) 6m = 96

$\tt\implies$ m = 96/6

$\tt\implies$ m = 16

Answer 2

Answer:

1) 3n+7 = 25

3n = 25-7

3n = 18

n = 18/3

n = 6

2) p-1 = 20

p = 20+1

p = 21

3) 6m = 96

m = 96/6

m = 16
