Answer:
(- 1, - 3 )
Step-by-step explanation:
Given the 2 equations
2x + y = - 5 → (1)
2x - 5y = 13 → (2)
Subtracting (1) from (2) term by term will eliminate the x-0 term
0 - 5y - y = 13 - (- 5) , that is
- 6y = 18 ( divide both sides by - 6 )
y = - 3
Substitute y = - 3 into either of the 2 equations and solve for x
Substituting into (1)
2x - 3 = - 5 ( add 3 to both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
solution is (- 1, - 3 )
I’m guessing 2 cups or something idk
Answer:
Step-by-step explanation:
If Adam's family uses 8lb of apples to make pie. We know that 3 x 8 = 24, so it's probably approximately 3 out of 18.
Answer:
x = -2
Step-by-step explanation:
<u><em>First, you need to subtract 8x from both sides:</em></u>
8x – 4 = 13x + 6
-8x -8x
____________
-4 = 5x + 6
<em><u>Then, subtract 6 from both sides:</u></em>
-4 = 5x + 6
-6 - 6
________
-10 = 5x
<u><em>Lastly, divide both sides by 5:</em></u>
-10 = 5x
-2 = x
