Question

wha is the solution to 2x-6y=7

Answer 1

This is an equation of 2 variables - you cannot simply solve for x and y, but you can express x as a function of y or y as a function of x.

Are you trying to solve for x, or for y?

Answer 2

for x

Answer 3

Okay - with any equation with only x you always try to isolate the variable first. since x(and not y) is your variable, what do you think you should do first?

Answer 4

solve for x I the solution is x=3y+7

Answer 5

ah - you are forgetting to divide the 7 by 2

Answer 6

oh yeah; it's x=3y+7/2

Answer 7

yup :)

Answer 8

this is a linear equation: so 2x-6y=7
5x+2y=10
