Alina [70]

Answer:

A= .75 B= .75

Step-by-step explanation:

Plug in .75. 5(.75) + 3(.75) = 6

7(.75) + 9(.75) = 12

You would turn a to x and b to y to get ---> 5x + 3y = 6 and 7x + 9y = 12 -----> then you would multiply the first equation  ^^^^^ by 3 to cancel to give you    15x + 9y = 18 (I did that to get 9y and cancel out the 9y in the other equation) next do 15x + 9y = 18 - 7x + 9y = 12 to get ----> 8x = 6 ---> divide by 8 to get --->     x = .75

Hope this helped!!
