Question

Solve the following equations

(a) 4 = 5 (p − 2)
(b) − 4 = 5 (p − 2)
(c) 16 = 4 + 3 (t + 2)

Answer 1

Step-by-step explanation:

(a) 4 = 5 (p − 2)

5 (p − 2) = 4

5p – 10 = 4

5p =4 + 10

5p = 14

P = 14/5

(b) − 4 = 5 (p − 2)

5 (p − 2) = -4

5p – 10 = -4

5p = -4 + 10

5p = 6

p = 6/5

(c) 16 = 4 + 3 (t + 2)

16 − 4 = 3 (t + 2)

12 = 3 (t + 2)

$\frac{12}{3}$ = t + 2

4 = t + 2

4 − 2 = t

2 = t

Answer 2

Answer:

P = 14/5

p = 6/5

2 = t
