The correct anwser is 12. The solution is 76/6 then you know it's 12.666666666... But we can't say that's 13 because they are human. So wecan only say the number is 12 not 13.
-30x + 16. You use the distributive property to get -24x + 28 -12 -6x. Then combine like terms to get -30x + 16.
<span>There are two solutions.. x=16</span><span> or </span><span>x=−<span>16.</span></span>
Answer:
The solution would be (10, -3)
Step-by-step explanation:
In order to solve using elimination, multiply the top equation by -3 and then add the equations together.
-9x - 12y = -54
9x - 5y = 3
---------------
17y = -51
y = -3
Now that we have a value for y, we can put it into either equation and solve for x.
3x + 4y = 18
3x + 4(-3) = 18
3x - 12 = 18
3x = 30
x = 10
