Let's solve each equation one by one:
1) 4.8 - x = 5.6Subtracting 4.8 from both sides:-x = 0.8Multiplying by -1 to find x:x = -0.8
2) 7 - x = -2.3Adding x to both sides:7 = x - 2.3Adding 2.3 to both sides:x = 9.3
3) 3x - 3.9 = -2.7Adding 3.9 to both sides:3x = 1.2Dividing by 3 to find x:x = 0.4
Therefore, the solutions of the equations are:x = -0.8, 9.3, 0.4
Let's solve each equation one by one:
1) 4.8 - x = 5.6
Subtracting 4.8 from both sides:
-x = 0.8
Multiplying by -1 to find x:
x = -0.8
2) 7 - x = -2.3
Adding x to both sides:
7 = x - 2.3
Adding 2.3 to both sides:
x = 9.3
3) 3x - 3.9 = -2.7
Adding 3.9 to both sides:
3x = 1.2
Dividing by 3 to find x:
x = 0.4
Therefore, the solutions of the equations are:
x = -0.8, 9.3, 0.4
