Find the number of solutions of the pair of equations x + 2y – 4 = 0 and 2x + 4y – 8 = 0
Answers
Step-by-step explanation:
Corrosion can be defined as the process through which refined metals are converted into more stable compounds such as metal oxides, metal sulfides, or metal hydroxides. The rusting of iron involves the formation of iron oxides via the action of atmospheric moisture and oxygen.
