Answer:
This equation has ONE unique solution, which is x = 1.
Step-by-step explanation:
Let's actually solve this equation, 0.9x+5.1x-7=2(2.5x-3).
Mult. all four terms by 10 to eliminate the fractions:
9x+51x-70=2(25x-30)
Perform the indicated multiplication:
9x+51x-70= 50x - 60
Combine like terms: 60x - 70 = 50x - 60 => 10x = 10, and x = 1
This equation has ONE unique solution, which is x = 1.
