Explanation:
the equation of a line in
slope-intercept form
is.
∙
x
y
=
m
x
+
b
where m is the slope and b the y-intercept
rearrange
x

y
=
6
into this form
subtract x from both sides
x
−
x

divide all terms by 3
⇒

Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
X=Y /2+ 5/2
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
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
