Answer:
D
Step-by-step explanation:
4x - 2(x + 3) = 8
Use distributive property
4x -2x - 6 = 8
2x - 6 = 8
2x = 8 + 6
2x = 14
x = 14 ÷ 2
x = 7
Answer is A.
You start by adding the 7 to the opposite side. Giving you 19. You divide both sides by -2 which gives you x on one side and -9.5 on the other.
-2x-7=12
-2x=12(+7)
-2x=19
x=19/-2
x=-9.5
7x-2(x+1)=6x+14
7x-2x-2=6x+14
5x-6x=14+2
-x=16
x=-16

Step-by-step explanation:
Any non-parallel lines in the plane must intersect in one place; thus, there is one solution to the system of equations.
