Question

Hi plssss solve this fast

Answer 1

3√343/729 + 9/4

=7/9 + 9/4

=109/ 36

x + a = 40

x = 40 - a

2x + 4a =150

2(40- a ) + 4a = 150

80 - 2a + 4a = 150

2a = 150 - 80

a = 70/2

a = 35

x = 40 -a

x = 40 - 35

x = 5

12x + 13y = 29

12x = 29 - 13y

13x + 12y = 21

29 - 13y + 12y = 21

- y = 21 - 29

-y = - 8

y = 8

12x = 29 - 13y

12x = 29 - 13(8)

12x = 29 - 104

x = - 75/12
