Answer: I think it's The Third Point Unsure
To isolate x , multiply both the sides by ( <u>5/23</u> )
<h3>What is an Equation ?</h3>
An equation is formed when two algebraic expressions are equated using an equal sign.
The given equation is
(3/5)(x-10) = 18-4x-1
(3/5)x - 6 = 18-4x-1
(3/5)x - 6 = 17-4x
(3/5)x = 23 -4x
(23/5)x = 23
Step 5 says To isolate x , multiply both the sides by <u>(5/23)</u>
x = 5

Okay this one is easy all you gotta do is look at the decimal point and the place its at.
<h3><u>This equation is wrong.</u></h3>
3(x + 12) does not, and never will, equal 3(x + 5)
We can solve the equation to verify.
3(x + 12) = 3(x + 5)
<em><u>Distributive property.</u></em>
3x + 36 = 3x + 15
<em><u>Subtract 15 from both sides.</u></em>
3x + 21 = 3x
<em><u>Cancel like terms.</u></em>
21 = 0 <u>× this is incorrect.</u>
