It is four. So two and two you add them together to be four. Good job. Your learning :)
Use elimination.
-x = -6
X = 6
-4 (6) + 4y = 12
Y = 9
(X,y)
(6,9) is the solution
2x-3+7x-10=32
9x-13=32
9x=32+13
9x=45
x=5
Answer:
4
Step-by-step explanation:
So we know that RT is 36.
Note that RT is the combined length of RS and ST. Therefore:

Substitute. RT is 36, RS is 6x+1 and ST is x+7:

Combine like terms and add:

Subtract 8 from both sides:

Divide by 7:

So, our answer is 4 :)
Answer:
X=10
A=84
Step-by-step explanation:
5x+34+2x+76=180
7x+110=180
7x=70
x=10
For A
5(10)+34
84
