Answer:
x = 25/3
Step-by-step explanation:
3/5x+7=12
Subtract 7 from each side
3/5x+7-7=12-7
3/5x = 5
Multiply each side by 5/3 to isolate x
5/3 *3/5x = 5*5/3
[tex]x = \frac{3}{25} \\ [/tex]
[tex] \frac{3}{5x} + 7 = 12 \\ \\ \frac{3 + 35x}{5x} = 12 \\ \\ 3 + 35x = 12 \times 5x \\ 3 + 35x = 60x \\ 3 = 60x - 35x \\ 3 = 25x \\ 25x = 3 \\ \\ x = \frac{3}{25} [/tex]
