Answer:
Step-by-step explanation:
The system of equations is expressed as
-x -3y =18 - - - - - - - - - - - - - -1
x + 2y = -14 - - - - - - - - - - - - - -2
We would eliminate x by adding equation 1 to equation 2. It becomes
- y = 4
Dividing the left hand side of the equation and the right hand side of the equation by - 1, it becomes
- y/ - 1 = 4/ - 1
y = - 4
Substituting y = - 4 into equation 1, it becomes
-x -3 × - 4 =18
- x + 12 = 18
Subtracting 12 from the left hand side of the equation and the right hand side of the equation, it becomes
- x + 12 - 12 = 18 - 12
- x = 6
x = - 6
Answer:
no solutions
Step-by-step explanation:
3x+ 7(x+1) = 2(6x+5) -2x
Distribute
3x+7x+7 = 12x+10-2x
Combine like terms
10x+7 = 10x+10
Subtract 10 from each side
10x+7-10x = 10x+10-10x
7 = 10
This is not a true statement so there are no solutions
