Answer:
The value of x is -4/5.
Step-by-step explanation:
First, you have to get rid of brackets, by expanding out :
2(6x+10) - 3x = 10 - (x-2)
2(6x) + 2(10) - 3x = 10 - x + 2
12x + 20 - 3x = 10 - x + 2
Next, is to bring all the x variable to one side :
12x + 20 - 3x = 10 - x + 2
12x - 3x + x = 10 + 2 - 20
10x = -8
Lastly, is to solve it by dividing 10 to both sides :
10x = -8
10x ÷ 10 = -8 ÷ 10
x = -4/5
If we do it algebraically, we get
x + y = 420
This is the simplest equation. You see now this is a linear pair in two variables. Thus, there will be infinitely many solutions.
E.g - 419 + 1 = 420
42 * 10 = 420
21 * 20 = 420
etc,....
Answer:(2,1/3)
Step-by-step explanation:
-x-3y=-3
2x+3y=5
_________First solve for x since y is 0. -3y+3y=0
1X = 2
1x/1= 2/1
X= 2
Now substitute your x answer into any equation to find y I used second equation
2x+3y= 5
2(2)+3y=5
4+3y=5
3y=5-4
3y=1
3y/3=1/3
Y=1/3
6+(-4) is almost like saying 6-4 which is 2
Same for 6+(-6) is just like 6-6 which is 0
