Answer:

x = 12

Step-by-step explanation:

Equation:    0.52(x) + 0.72(4) = 0.57(x + 4)

0.52(x) + 0.72(4) = 0.57(x + 4)             \longmapsto         Multiply

0.52x + 2.88 = 0.57x + 2.28               \longmapsto         Subtract 0.52x from both sides

2.88 = 0.05x + 2.28                            \longmapsto         Subtract 2.28 from both sides

0.6 = 0.05x                                          \longmapsto        Divide all sides by 0.05

 

x = 12
