Please help! Identify a reasonable approximation for the solution of this system. The solution will be between these two x-values. 0.6 and 0.7. But how am I supposed to write the approximation without knowing if it's wrong?

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

b is the right answer
