3x-5=-6x+13 : Given
3x=-6x+18 : Addition property of Equality
9x=18: Subtraction property of Equality
x=2: Division Property of Equality
Step-by-step explanation:
We need to give justification to each step
Step 1:
3x-5=-6x+13
This is the question given, which we need to solve and find value of x.
Justification: Given
Step 2:
Adding 5 on both sides of the equation using addition property of equality.
3x-5+5=-6x+13+5
Simplifying
3x=-6x+18
Justification: Addition property of Equality
Step 3:
Adding 6x on both sides of the equation
3x+6x=-6x+18+6x
9x=18
Justification: Subtraction property of Equality
Step 4:
Divide both sides of the equation by 9, to find the value of x using division property of equality
9x/9=18/9
x=2
Justification: Division Property of Equality

8 ( x - 3 ) = *8x + -24* or *8x - 24* (theyre the same thing) what You do is just distribute the 8 to ALL numbers inside parantheses. Hence, 8 times x is *8x* and 8 times a negative -3 is *-24*. Hope i helped!
<span>The correct statement or mathematical
expression in the choices given is:
900 is 100 times as much as 9.</span>
<span>
Because if you multiply 9 x 100 (100
times as much as 9) = 900.</span>
Hence,
<span><span>1. </span>1/10 of 100 = 10 </span>
<span><span>
2. </span>1000 times as much as 90 or 1000 x 90 = 90, 000</span>
<span><span>
3. </span>9 is 1/10 of 900 or 900 is divided by 10: 900 / 10 = 90</span>
