Answer:
Step-by-step explanation:
(x-3)/(x+4) = x/(x+10)
(x-3)(x+10) = x(x+4)
x²+7x-30 = x²+4x
3x = 30
x = 10
Answer:
Step-by-step explanation:
butt
A-2b=-10
add 2b on both sides
a=2b-10
add 10 to both sides
a+10=2b
divide both sides by 2
a/2+10/2=a/2+5=b
b=5+a/2
Answer:
x = 0 or 1 or -2
Step-by-step explanation:

x(x^3-3x+2)=0
x(x-1)^2 * (x+2)0
so x = 0 or 1 or -2
there is no imaginary solutions
1/2(2x+6)
Substitute the one half to both of the numbers inside the parentheses.
1/2*2 is one which would just be x
1/2*6 is three
X+3
