Answer 1

Step-by-step explanation:

a)

$10p = 100 \\ \\ p = \frac{100}{10} =1 0.$

b)

$10p + 10 = 100 \\ \\ 10p = 100 - 10 \\ \\ 10p = 90 \\ \\ p = 9.$

C)

$\frac{p}{4} = 5 \\ \\ p = 20.$

D)

$- \frac{p}{3} = 5 \\ \\ p = - 5 \times 3 \\ \\ p = - 15.$

e)

$\frac{3p}{4} = 6 \\ \\ p = \frac{6 \times 4}{3} \\ \\ p = 2 \times 4 \\ \\ p = 8.$

f)

$3s = - 9 \\ \\ s = \frac{ - 9}{3} \\ \\ s = - 3.$

g)

$3s + 12 = 0 \\ \\ 3s = - 12 \\ \\ s = \frac{ - 12}{3} \\ \\ s = - 4.$

h)

$3s = 0 \\ \\ s = 0.$

I)

$2q = 6 \\ \\ q = \frac{6}{2} \\ \\ q = 3.$

j)

$2q - 6 = 0 \\ \\ 2q = 6 \\ \\ q = 3.$

k)

$2q + 6 = 0 \\ \\ 2q = - 6 \\ \\ q = \frac{ - 6}{2} \\ \\ q = - 3.$

l)

$2q + 6 = 12 \\ \\ 2q = 12 - 6 \\ \\ 2q = 6 \\ \\ q = \frac{6}{2} \\ \\ q = 3.$
