Answer:
<h2>2x-2y = 6</h2><h2 />
Step-by-step explanation:
x-y=3
then 2×(x-y)=2×3
then
2x-2y = 6
X-13=42
x is the "variable", you're taking 13 away from that, and the answer is also given, 42.
Answer:
-1/6 for the number 6 and 2/3 for -3/2
Step-by-step explanation:
You have to do the reciprocal, or just swap the numerator and denominator. but if the parallel is positive the reciprocal becomes a negative. If the parallel is negative, then the reciprocal is positive.
Glad I could help!
Answer: x = 14/23
Step-by-step explanation:
3x-6=4(2-3x)-8x
3x-6=8-12x-8x --> Expand 4(2-3x)
3x-6=8-20x --> Collect like terms
3x-6+6=8-20x+6 --> Add 6 to both sides, to remove it from the right side
3x=-20x+14
3x+20x=-20x+14+20x --> Add 20x to both sides, to remove it from the left side
23x=14
--> Divide both sides by 23
x = 14/23
Answer:
