Answer:

r = 5/8(q)

Step-by-step explanation:

−7q + 12r = 3q − 4r

Add 4r to both sides:

−7q + 12r + 4r = 3q − 4r + 4r

−7q + 16r = 3q

Add 7q to both sides:

−7q + 16r + 7q = 3q + 7q

16r = 10q

Divide both sides by 16:

(16r)/16 = (10q)/16

r = 5/8(q)

How do I factor quadratics?
nekit [7.7K]

Ok so factoring quadratics is fairly easy once you get the hang of it

So we have a quadratic x^2+x-2

My first question would be what 2 numbers multiply to -2 and add to +1

the answer is 2 and -1

Second question what 2 values multiply to get x^2

the answer x and x

your factored form would be (x-1)(x+2)

This is as far as i can explain there is a whole lot about quadratics to be learned. You have to ask your teacher on more information
