Answer:
x = -2
Step-by-step explanation:
The given equation is a multi-step equation since it has the variable on both sides of the equal sign. However, the goal of any equation is to isolate the variable (get it by itself) by using inverse (opposite) operations to get the variable on one side of the equal sign and the numbers on the other.
5x - 5 = 3x - 9
1. Subtract '3x' from both sides:
5x - 3x - 5 = 3x - 3x - 9
2x - 5 = -9
2. Add '5' to both sides:
2x - 5 + 5 = -9 + 5
2x = -4
3. Divide '2' from both sides:
2x/2 = -4/2
x = -2

Answer:
a.
b.
Step-by-step explanation:
We have a differential equation
y''-2 y'-35 y=0
Auxillary equation
By factorization method we are finding the solution
Substitute each factor equal to zero
D-7=0 and D+5=0
D=7 and D=-5
Therefore ,
General solution is
Let
We have to find Wronskian
Substitute values then we get
a.
We are given that y(0)=-7 and y'(0)=23
Substitute the value in general solution the we get
....(equation I)
......(equation II)
Equation I is multiply by 5 then we subtract equation II from equation I
Using elimination method we eliminate
Then we get
Substitute the value of in I equation then we get
Hence, the general solution is
b.
