Question

Hello everyone!

Don’t actually solve this, but can you give me the actual steps I would take to solve it? Thanks!

7x+3y=18
3x+7y=18
Solve for x, y
(not real problem)

Answer 1

either use substitution or elimination

Explanation:

eg for substitution

make 7x+3y=18 into

7x = 18-3y,

x = (18 - 3y)/7

then input into 2nd equation to find y

ie 3[(18 - 3y)/7] +7y =18

solve to find y

then use ans in y to find x using either equation
