Answer:
x=7
Step-by-step explanation:
expand 4(x+5): 4x+20
2x+34=4x+20
subtract 34 from both sides
2x+34-34=4x+20-34
2x=4x-14
subtract 4x from both sides
2x-4x=4x-14-4x
-2x=-14
divide both sides by -2
-2x/-2=-14/-2
x=7
Using the quadratic formula, we have:

, so our solutions are

and

.

plz mark me brainliest. :)
A=b/c -b/d
a+b/d=b/c
(da+b)/d=b/c
db=(da+b)c
c=db/da+b
Answer is c just in place of x subst x values and your y will come out
