x - number of working hours for parents
y - number of working hours for a computer company
{x + y = 40
{8x + 20y = 464
{x = 40 - y
{8(40 - y) + 20y = 464 || : 4
{x = 40 - y
{2(40 - y) + 5y = 116
{x = 40 - y
{80 - 2y + 5y = 116
{x = 40 - y
{80 + 3y = 116 || - 80
{x = 40 - y
{3y = 36 || : 3
{x = 40 - y
{y = 12
{x = 40 - 12
{y = 12
{x = 28
{y = 12
Answer:
9
Step-by-step explanation:
2,3,4,7,7,7,9,9,14,17,21
