Question

X+3Y=6
Y=2X-5
What is the solution or if there’s infinitely solutions or no solution

Answer 1

first solve x + 3y = 6 for y

this would be y = (x+6)/3

then plug that y value into the other formula

(x+6)/3 = 2x - 15

then just solve for x

answer: x = 21

Answer 2

Answer: slope

y-intercept

=

2

Explanation:

the equation of a line in

slope-intercept form

is.

∙

x

y

=

where m is the slope and b the y-intercept

rearrange

into this form

subtract x from both sides
