Let's solve the first equation:
-6(-5-7x) = -8x + 230 + 42x = -8x + 250x = -28x = -28/50x = -14/25
Now let's solve the second equation:
9 + 2(2x + 1) = 19 + 4x + 2 = 14x + 11 = 14x = -10x = -10/4x = -5/2
So the solution to the system of equations is:x = -14/25x = -5/2
Let's solve the first equation:
-6(-5-7x) = -8x + 2
30 + 42x = -8x + 2
50x = -28
x = -28/50
x = -14/25
Now let's solve the second equation:
9 + 2(2x + 1) = 1
9 + 4x + 2 = 1
4x + 11 = 1
4x = -10
x = -10/4
x = -5/2
So the solution to the system of equations is:
x = -14/25
x = -5/2
