Question

-4a-6u=6, a-5u=18 plzz say this any one plz give correct answer​

Answer 1

Answer:

A=3 and U= -3

Step-by-step explanation:

Start with

A-5U = 18

A=18-5U

PUT Value of A in first eqn

-4(18+5U)-6U = 6

2(-2(18+5U)-3U) = 6

-36-10U-3U = 6/2

-36-13U=3

-13U=3+36

-13U=39

U= -39/13

U= -3

PUTTING value of U in second eqn

A-5(-3)=18

A-15=18

A=18-15

A=3
