Answer:
1
Step-by-step explanation:
In this system of equations, I'll do elimination. Ok, so what we are trying to do is to eliminate a variable, but we can't. So since -2y is negative, and y has a coefficient of 1 and is positive, let's multiply the first whole equation by 2.
2 times (3x+y=11) is 6x+2y=22. (I just used distributive property.) Now let's add from left to right.
6x plus x is 7x, 2y plus -2y is 0, and 22 plus 6 is 28. Now we have this simple equation, 7x=28. We can simply divide each side by 7, to get x as 4. So x=4 in this set of equations. Now all we need to do is plug x in the equation then solve for y. For this system of equations, I'll use the first equation, because it is easier. So I'll plug x as 4 into the equation to get 12+y=11. Now we can simply solve for y. 11-12 is -1, so y must equal -1. So y=-1. Therefore, x=4 and y=-1. Hope I helped.
Answer:
The answer for this is.. x= 5/3 the decimal is x=1.66666..
Step-by-step explanation:
Expand -3(x-2) : -3x+6
x-3x+6=4(x-1)
Add similar elements: x-3x= -2x
-2x+6=4(x-1)
Expand 4(x-1): 4x-4
-2x+6= 4x-4
Subtract 6 from both sides
-2x+6-6= 4x-4-6
Simplify
-2x-4x-10
Subtract 4x from both sides
-2x-4x=4x-10-4x
Simplify
-6x=-10
-6x/-6 = -10/-6
so the answer is x-5/3
