Answer:
20
Step-by-step explanation:
Vertical angles are always equal to each other. So the answer is
3x + 4 = 73 - 9 Are you sure this is what the question is?
3x + 4 = 64 Subtract 4 from both sides
<u> -4 -4</u>
3x = 60 Divide by 3
3x/3 = 60/3
x = 20
Answer:
f(x)
Step-by-step explanation:
f(x)=x-1/x+5
y=x-1/x+5
xy+5y=x-1
xy-x=-1-5y
x(y-1)=1-5y
x=-1-5y/y-1
x=-5
Answer:
x = 12/5
Step-by-step explanation:
take the square of both sides
(x^2+49) = (x+5)^2
x^2 + 49 = (x+5) (x+5)
x^2+49= x^2 + 10x + 25
10x + 25 = 49
10x = 24
x = 12/5
