sergiy2304 [10]

Answer:

Solving,

Combine the like terms and adding those terms

$(6x^3+3x^2-2)+(x^3-5x^2-3)\\=6x^3+3x^2-2+x^3-5x^2-3\\=6x^3+x^3+3x^2-5x^2-2-3\\=7x^3-2x^2-5$

So, the answer is:

$7x^3-2x^2-5$

Solve the following simultaneous equations: 1. a) x-y=-5 and x + y = -1

Sonbull [250]

Answer:

x = -3, y = 2

Step-by-step explanation:

x - y = -5

x = -5 + y

Let's put this into the other equation

(-5 + y) + y = -1

-5 + 2y = -1

2y = 4

y = 2

Now we can solve for x by plugging y into either equation

x + (2) = -1

x = -3
