Answer:
B) -1
The 'x' value =-1 and y =-7
The solution of the given system of equations
(-1,-7)
Step-by-step explanation:
<u><em>Step(i)</em></u>
Given that the system of equations
x-y = 6 ..(i)
y = 2x -5 ..(ii)
By using substitution method,
substitute y=2x-5 in equation (i) , we get
x -(2x-5) =6
x -2x+5 =6
-x = 6-5
-x =1
x=-1
<u><em>Step(ii):-</em></u>
Put x=-1 in equation (ii) , we get
y = 2(-1) -5 = -2-5 =-7
The solution of the given system of equations
(-1,-7)
Answer:
Char's monthly payment for the TV was $182.56.
Step-by-step explanation:
To find the answer, first you have to subtract the down payment from the cost of the TV:
$1,345.36-$250=$1,095.36
Then, you have to divide the remaining amount by six to find the monthly payment:
$1,095.36/6=$182.56
According to this, the answer is that Char's monthly payment for the TV was $182.56.
Answer:
x =- 3 and y = -7
Step-by-step explanation:
2X-2Y=-8
X=2y + 11
We need to isolate both X and Y in both equations
so
2x-2y=-8
(add 2y to both sides)
2x=-8+ 2y
(divide both sides by 2)
x=-4+y and x=2y+11
because <u>both of these equations are the same </u>we can put them together
4+y=2y+11
(subtract y)
4=y+11
(subtract 11)
-7=y
so y = -7
then to find x you just need to plug in y to one of the equations
x=2(-7) + 11
x= -14 +11
x = -3
