Question

Solve the following system by using graph paper or graphing technology 2x+3y=3 3x-2y=11

Answer 1

solve each equation for y. (put y on the right side by itself without any coefficients). that's the first step.

Answer 2

since we can not use substitution or elimination we have to get the two equations of the lines in y = mx+b format.

Answer 3

I need to create an equation and the use it to solve for the problem.

Earnings E are directly proportional to time T worked, and E is $45 when T is 3hours. How long has a person worked is she earned $455?

Answer 4

E = Tk

45 = 3k

k = 15

// now use the fact that she has earned 455 and the k we found to find T. post what you get.
E = Tk

Answer 5

445=15T then just solve it right?

Answer 6

yes.

Answer 7

actually 455
