Answer:
(-4, 5)
Step-by-step explanation (work shown in attached picture):
1) Since x is already isolated in the first equation, substitute that value for x into the other equation to find y. So, substitute 16-4y for the x in 3x + 4y = 8, then solve for y. This gives us y = 5.
2) Now, substitute that given value for y back into any one of the equations to find x. I chose to do it in the first equation. Substitute 5 for the y in x = 16-4y, then solve for x this time. This gives us x = -4.
Since x = -4 and y = 5, the solution is (-4, 5).
Answer:
(8n^4-6n+8n^2)+(6n^4-4)
8n^4 + 8n^2 - 6n + 6n^4 - 4
<u>14n^4 + 8n^2 - 6n - 4</u>
Step-by-step explanation:
7.60, 1.90 times 3 is 5.7 and then you add alicias money to that and it makes 7.6
