First= -2x+2y+3z=0
= -2x+2y+3z +-2y=0+(-2y)
-2x+3z=-2y
-2x+3z=-2y+-3z
-2x=-2y-3z
Divide both by negative two
-2x/-2=-2y-3z/-2
x=y+3/2z that’s the answer.
Use this to help you with other equations
Answer:
x = -1/2 , 4
Step-by-step explanation:
1) If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
2x+1=0
x−4=0
2) Set the first factor equal to 0.
2x+1=0
3) Subtract 1 from both sides of the equation.
2x=−1
4) Divide each term by 2 and simplify.
2x/2= −1/2
5) Cancel the common factor of 2.
x= −1/2
6) Move the negative in front of the fraction.
x = −1/2
7) Set the next factor equal to 0 and solve.
x=4
8) The final solution is all the values that make
(2x+1)(x−4) = 0 true.
9) x = −1/2 , 4
+8 means that it is a positive number
-8 means that it is a negative number
I think what you mean by: {8}, is |8| which is absolute value which means no matter the answer it is the absolute value from 0 so it’s always +
First, set the coordinate points on a graph, and joint them to form a graph
By looking at the graph we can see that:
width : 3
length: 6
Area of a rectangle : Length x width : 6 x 3 = 18
Answer:
Step-by-step explanation:
we have
Solve for h
That means ----> isolate the variable h
step 1
Multiply by 6 both sides
step 2
Divide by 
both sides
