Answer:

10-7a

Step-by-step explanation:

Break the brackets by expanding. Two minus makes one plus.

13a-(-4)+6-20a = 13a+4+6-20a

Evaluate like terms.

13a+4+6-20a = 10-7a

What is the value of the y-coordinate of the solution to the system of equation 2x+y=8 and x-3y=-3
r-ruslan [8.4K]
1) 2x + y = 8                           2) x - 3y = -3
    y = -2x + 8                              y = -x - 3 / -3

Solve the following system:
Angelina_Jolie [31]
You can rewrite the second equation because you know what y equals, so you can write it as 2x + x + 3 = 9
3x + 3 = 9
- 3
3x = 6
÷ 3
x = 2

And now you use the equation of what y equals and substitute in the value of x, so y = 2 + 3
y = 5

So your final answer is A. (2, 5). I hope this helps!
