If the solution exists, y=y....

3x+2=-x/4+1 make everything have a common denominator of 4...

(12x+8)/4=(-x+4)/4 now multiply both sides by 4

12x+8=4-x add x to both sides

13x+8=4 subtract 8 from both sides

13x=-4 divide both sides by 13

x=-4/13

x≈-0.31 and the only pair in your choices having an x value close to that is:

(-0.3, 1.1)

2x-3/x devided by 7/x^2

Sergio039 [100]

Answer:

$\frac{2x^2-3x}{7}$

Step-by-step explanation:

$\frac{2x-3}{x}$ ÷ $\frac{7}{x^2}$

=> $\frac{2x-3}{x}$ × $\frac{x^2}{7}$

=> $\frac{2x-3}{7}$ × $\frac{x^2}{x}$

=> $\frac{x(2x-3)}{7}$

=> $\frac{2x^2-3x}{7}$
