1 answer:

8 0

Here is how you solve...

Q= 3a+5ac

take out the common variable.
Q= a(3+5c)

get A by its self so divide each side by (3+5c).
Q/a(3+5c)= a(3+5c)/(3+5c)

Q/a(3+5c)=A

So your answer is A= Q/a(3+5c)

hope that helped.

X + 6y = 2 4x - 3y = 10 Pick the first step to solving this system of equations using the addition method.

podryga [215]

This one is the correct answer----->Multiply the bottom equation by 2 thus eliminating the y variable when the equations are added together.

X + 6y = 2 ....top
4x - 3y = 10...bottom

if we multiply the bottom equation by 2 .......... => 8x - 6y = 20
if we add it to the top one..........>(8+1)x +(6-6)y = (20+2)
then we solve for x => x = 22/9

then with the top equation, we solve for y == > y = -2/27
