Answer:
x = 13.5
Step-by-step explanation:
2/11 = 3/(3 + x)
6 + 2x = 33
2x = 27
x = 13.5
The equation is 1/2+3/x=3/4, it is still solvable
the equivalent of the equation is (1.x+2.3)/2.x = 3/4, or (x+ 6)/2.x=3/4, this last can be solved as follow: 4.(x+ 6) = 2x.3, 4x+ 24 = 6x, so 24=6x-4x=2x, and when 2x= 24 , it means x=24/2 =12, finally the equation is solvable because x=12 is a solution
Answer:1.07
Step-by-step explanation:
You just have to divide 3.21/3 and your get 1.07 and to make sure you multiply the 1st number by 1.07 and your get the second number.
Answer: the following system of equations has 2 solutions
x1=4
X2=-2
Step-by-step explanation:
5*x+4=x²+3*x-4
x²-2*x-8=0
x12=(2+/-√4+4*1*8)/2
x12=(2+/-√36)/2
x1=(2+6)/2=4
x2=(2-6)/2=-2
