Answer: Addition property of equality
Step-by-step explanation:
Assuming you meant 3x-9=2x+5, it would be the addition property of equality since you are adding 9 to both sides.
Is there a fraction or a number line to explain you question?☺
Answer:
because either x-6=0 or x+1=0
x-6=0
x=0+6
x=6 OR,
x+1=0
x=0-1
x=-1
Step-by-step explanation:
The answer is .75 because this is a proportion problem so cm over miles is 1 over 2 equals x over 1.5 you cross multiply and get 2x=1.5 and divide both sides by 2 and you get x=.75
Answer:
<h3>A. no solution</h3>
Step-by-step explanation:
<u>Given:</u>
Isolate the term of x and y from one side of the equation.
<h3>x-y=-4 and -2x+2y=6</h3>
x-y=-4
<u>First add by y from both sides.</u>
x-y+y=-4+y
<u>Solve.</u>
x=-4+y
<u>You have to substitute of x=-4+y.</u>
<u>Solve.</u>
<u>Use the distributive property.</u>
<u>Distributive property:</u>
⇒ A(B+C)=AB+AC
-2(-4+y)
Multiply expand.
-2*-4=8
-2*y=-2y
Rewrite the expression down.
8-2y
8-2y+2y=6
-2y+2y=0
8=6
- <u>Therefore, the correct answer is "A. No solution".</u>
I hope this helps, let me know if you have any questions.
