4x + 2 - 3x + 5 - 2(x + 5) = (2x - 5) + (3x + 4)
4x + 2 - 3x + 5 - 2x - 10 = 2x - 5 + 3x + 4
4x - 3x - 2x + 5 + 2 - 10 = 2x + 3x - 5 + 4
- x - 3 = 5x - 1
-x - 3 = 5x - 1 is the line above recopied
+x = +x
-3 = 6x - 1
<span> +1 = + 1 </span>
- 2 = 6x
- 2/6 = 6x/6
- 1/3 = x, the answer
Find two numbers with a sum of 20 and a difference of 14
Make two equations
X+Y=20
X-Y=14
Now add x since y cancels out and add 20+14 To end up with
2x=34
Now divide 2 both sides to get x alone
2x/2=34/2
X=17
Now substitute x answer to first equation and solve for y
17+y=20
Subtract 17 both sides
Y= 3
Your two numbers are
3 and 17

yes
Answer:
1 + 12
Step-by-step explanation:
Let's do this one step by step!
We are going to make sure that we pay attention to the part in the parenthesis first!
Let's multiply -2x with -6 first.
Equation:
4+(-3)-2x(-6)
We do not need to parenthesis around the -3 because a negative cancels out a positive. So, no matter what you would have to subtract.
4 - 3 + 12x
And we get a positive 12 because both numbers that were being multiplied were negative.
Now let's combine common terms.
1 + 12x
This is your answer! I hope this helped!
