Question

solve each equation and verify the solution.​

Answer 1

Step-by-step explanation:

(a) 32.3= m-6.9

m= 32.3+6.9=39.2

(b) b+19=12

b=12-19= -7

(c) -76.05=-9b

b =-76.05/-9=8.45

(d) w/-4=9

w=-4×9=-36

Answer 2

Answer:

a) 32.3 = m - 6.9

32.3 + 6.9 = m

39.3 = m

----> Proof :-

m - 6.9 = 32.3

39.3 - 6.9 = 32.3

32.3 = 32.3

LHS = RHS

b) b + 19 = 12

b = 12 - 19

b = - 7

----> Proof:-

b + 19 = 12

- 7 + 19 = 12

12 = 12

LHS = RHS

c) - 76.05 = - 9b

- 76.05 / - 9 = b

8.45 = b

----> Proof:-

- 9 × b = - 76.05

- 9 × 8.45 = - 76.05

- 76.05 = - 76.05

LHS = RHS

d) w / - 4 = 9

w = 9 × - 4

w = - 36

----> Proof:-

w / - 4 = 9

- 36 / - 9 = 4

4 = 4

LHS = RHS
