2 1/2 +2 1/2 + 2 1/2 + 2 1/2 + 2 1/2 + 2 1/2 + 2 1/2 + 2 1/2=20
Answer:
Step-by-step explanation:
1. 6x + 10 = 6x - 8
10≠-8
no solution
2. 6x + 8 = 2x - 6
4x + 8 = -6
4x = -14
x = -14/4= -7/2 one solution
3. 9x - 27 = 9x - 27
0 = 0 All real no. infinitely many solution

Answer:
Step-by-step explanation:
to solve this system of equations we will add them
x-3y=-12
2x+3y=3 now +3y-3y=0
3x=-12+3
3x=-9
x=-3
plug in the first equation
-3-3y=-12
-3y=-12+3
-3y=-9
y=3
