Find the sum and simplify the following expressions.
(s + 10) + (5s – 6)

12s

First, you have to do s+10 which is 11s because it’s always an invisible one infront of an variable without an number.

Next, you do 5s-6 which is 1s.

Finally, you do 11s+1s which gives you 12s

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
