Question

I need help with 3 question in math

Answer 1

Are the three sets of numbers on top a system of linear equations?

Answer 2

this is simple algebra. Isolate the variable by doing the inverse on one side of the function to the other. example:

\[2x-26=10\]
\[2x=36\]
\[x=18\]
Do that for the others and you get x=-1 and x=5
then for the last problem x=350

Answer 3
