Answer:
x < -39
Step-by-step explanation:
d/13 is actually just 1/13d:
1/13d > -3
Then you multiply both sides by the reciprocal of 1/13 which is 13. You do this because you normally you would divide, but since you can't divide a fraction, you multiply by the reciprocal, which is just the flipped version.
13 × 1/13 > -3 × 13
It cancels out on one side, because you are multiplying by its opposite. Then you multiply 13 × -3. This is -39. But the thing is that, when you multiply or divide by a negative, you need to flip the inequality sign around.
x < -39

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>

Answer: x=-2(-y+4)</h2>
Step-by-step explanation:
-2x+4y=16
Subtract 4y from both sides
-2x+4y-4y=16-4y
Simplify
-2x=16-4y
Divide both sides by -2
-2x/-2=16/-2- 4y/-2
<h2>
x=-2(-y+4)</h2>
