Answer:
1. No solution
2. Infinite solutions
Step-by-step explanation:
1. To solve the system, set the equations equal to each other and solve for x.
2x - 5 = 2x + 7
-5 = 7
This is a false statement. This means there is no solution.
2. To solve the system, graph each equation.
y = -3/4 x - 5/2 has a y-intercept -5/2 and slope -3/4.
3x + 4y = -10 converts to y = -3/4x -5/2.
This graphs as the exact same line. This system has infinite solutions.

The answer is 12 a this is how to solve it:
5a+3a+14+4(a-6)+10
5a+3a+14+4a-24+10
8a+14+4a-24+10
12a+14-24+10
12a-10+10
12a
