Question

What is the solution (a, b) to this system of linear equations?

Answer 1

Answer:

a=1, b=7. (1, 7).

Step-by-step explanation:

3a+6b=45

2a-2b=-12

-----------------

simplify 3a+6b=45 into a+2b=15

and 2a-2b=-12 into a-b=-6

--------------------

a+2b=15

a-b=-6

--------------

a+2b=15

-(a-b)=-(-6)

-----------------

a+2b=15

-a+b=6

---------------

3b=21

b=21/3

b=7

a+2(7)=15

a+14=15

a=15-14

a=1
