-8a+17b-4c+8

steps:
when there is a "+" in front of the parenthesis the expression remains the same.

7a+8b-15a+9b-4c+8

Collect the like terms

7a+8b-15a+9b-4c+8

7a and 15a
8b and 9b

15a-7a= -8a
9b+8b= 17b

Final answer:

-8a+17b-4c+8

Slove the system<br> Of Linear Eqitions by<br> Elimination <br> 3x-y=0<br> 2x+y=-10
Arlecino [84]

Answer:

<em>(-2, -6)</em>

Step-by-step explanation:

Given the simultaneous equation

3x-y=0 ... 1

2x+y=-10 ... 2

Add both equations to eliminate y

3x + 2x = 0 - 10

5x = -10

x = -10/5

x = -2

Substitute x = -2 into 1

3(-2)- y = 0

-6 - y = 0

-y = 0+ 6

-y = 6

y = -6

<em>Hence the coordinate (x, y) is (-2, -6)</em>

Sum of two numbers = 16 Difference of the numbers = 6 Find the numbers. What if their product?
Oksana_A [137]
Numbers x and y
sum of the two = 16: x + y = 16
difference of the two = x - y = 6
solve one of the equations for one variable:
I'm going to solve x - y = 6, for x
(x - y) + y = 6 + y, x = y + 6
Now plug that into the other equation:
x + y = 16, (y+6) + y = 16
(y+y) + 6 = 16
2y + 6 - 6 = 16 - 6
2y = 10
2y/2 = 10/2
y = 5
Now plug that solved y-value into either original equation: x - y = 6, x - 5 = 6
(x-5) + 5 = 6 + 5
x = 11
So now we have their values: x=11, y=5
But always double-check what the question asked... What is their product??
So x*y = 11*5 = 55
