Let x be kindergarten students

x = 420 - [(0.25*420) + (0.2*420)+115]

x= 420 - (105 + 84 + 115)

x= 420 - 304

x= 116 kindergarten students

Solve for x &amp; y. 30x−42y=−6 and 5x−7y=−1
vladimir1956 [14]
Um.. Both of those equations are the exact same. Divide both sides of the first equation by 6. You get:

\frac{30x  - 42y}{6} = \frac{-6}{6} \\ 5x - 7y = -1

That is the exact same as the second equation. This system has an infinite number of solutions. 5x - 7y = -1 is a line, so basically every point on that line is a solution to the system.

For example, x = 0 and y = \frac{1}{7} would work, but so would x = 1 and y = \frac{6}{7}
