For the first equation:
-12 + 7 + x - 5.3 = 0.9-5.3 + x = 5.1x = 10.4
For the second equation:
0.3 - 7.2 - x = -1.5-6.9 - x = -1.5x = 5.4
Therefore, the solution to the system of equations is x = 10.4 for the first equation and x = 5.4 for the second equation.
For the first equation:
-12 + 7 + x - 5.3 = 0.9
-5.3 + x = 5.1
x = 10.4
For the second equation:
0.3 - 7.2 - x = -1.5
-6.9 - x = -1.5
x = 5.4
Therefore, the solution to the system of equations is x = 10.4 for the first equation and x = 5.4 for the second equation.
