2 - 5x > 0 and -4x + 3> 0
<span>log8(2-5x)=log8(-4x+3) <=> 2 - 5x = - 4x + 3 <=> -5x + 4x = 3 - 2 <=> -x = 1 <=> x = -1;
</span>
2 - 5(-1) = 7 > 0 and -4(-1) + 3 = 7 > 0 ;
the solution is -1;
Answer:
14. 12x + 2y
16. -2x - 4y
18. -8x + 10y
Step-by-step explanation:
<h3><u>
Don't stress it.</u></h3>
All you need to do is add the x's with the x's and add the y's with the y's.
The same applies with subtraction.
<u><em>Note: </em></u>
positive + positive = positive
negative - negative = negative

Answer:
Step-by-step explanation:
1,)
3x+y=4 <-Equation 1
2x-y=6 <-Equation 2
Step 1 Eliminating Y Multiply negative both side
-[3x +y = 4 ] -
-3x-y = -4 <-Equation 3
Equation 2 to Equation 3
2x-y=6
-
-3x-y = -4
= 5x = 10
x =2
Substituting X to Equation 1
3x+y=4
3(2) + y =4
6 + y = 4
y = -2
Therefore x =2 and y = -2
Answer:
w ≤ 13
Step-by-step explanation:
-2(w-4) ≥ -18
Divide both sides by -2:
w-4 ≤ -18/-2
Don't forget to turn the inequality around, because we divided by a negative number!! We had greater than, now we have less than.
w-4 ≤ 9
Add 4 to both sides:
<u>w ≤ 13</u>
