Question

3. Solve the following equations by trial and error method:
(1) 5p + 2 = 17 (i) 3m- 14 = 4

Answer 1

Hope it is helpfull

$1)5p + 2 = 17 \\ 5p = 17 - 2 \\ 5p = 15 \\ p = 15 \div 5 \\ p = 3 \\ 2)3m - 14 = 4 \\ 3m = 4 + 14 \\ 3m = 18 \\ m = 18 \div 3 \\ m = 6$

Answer 2

Step-by-step explanation:

a)

$5p + 2 = 17$

$5p = 17 - 2$

$5p = 15$

$p = \frac{15}{5}$

$p = 3$

b)

$3m - 14 = 4$

$3m = 4 + 14$

$3m = 18$

m=18÷3

$m = 6$
