3/5 (10+5x)−1/3(6x+3)=9 ok answer fast

x = 4

Step-by-step explanation:

multiplied by common denominator

3(10 + 5x)(3) - 1(6x + 3)(5) = 9(15)   reduced all fractions

90 + 45x - 30x - 15 = 135      distributed

15x + 75 = 135      simplified (added like terms)

15x = 60         subtracted 75 from both sides

  x = 4          divided 15 from both sides

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
