For the following system, use the second equation to make a substitution for x in the first equation. x + 5y - 10 = 0, x = 2y - 8 What is the resulting equation in simplest form? -3y-18=0, 3y-18=0, 7y-18=0

Don’t worry about it

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
