The second step is to keep your x terms on the left and move the constant to the right by subtracting it from both sides.
Answer:
Step-by-step explanation:
So we have the system:
If we isolate the x-variable in the first equation:
Subtract 2y from both sides:
Divide both sides by -1:
Therefore, we would substitute the above into the second equation:
The answer is 2y+6
Further notes:
To solve for the system, distribute:
Simplify:
Subtract:
Divide:
Now, substitute this value back into the isolated equation:
10 cars are silver, 20% of 50 is 10
Answer:700,000+80,000+4,000+200+20+9
Step-by-step explanation:
That should be the answer.
Answer:
x = 73/4
Step-by-step explanation:
Solve for x:
12 x - 39 = 180
Add 39 to both sides:
12 x + (39 - 39) = 39 + 180
39 - 39 = 0:
12 x = 180 + 39
180 + 39 = 219:
12 x = 219
Divide both sides of 12 x = 219 by 12:
(12 x)/12 = 219/12
12/12 = 1:
x = 219/12
The gcd of 219 and 12 is 3, so 219/12 = (3×73)/(3×4) = 3/3×73/4 = 73/4:
Answer: x = 73/4
