3x+7y=-6 -7x+3y=26 -4x+4y=-32 +4x on both sides and you end up with 4y=-32+4x now divide both sides by 4 and you get y=-8+x then to incorporate that in one of the problems 3x+7(-8+x)=-6 do the distributive property with the 7 into the () and you get 3x-56+7x=-6 now add all common variables and get 10x-56=-6 now add 56 to both sides and you get 10x=50 now divide by 10 on both side and you get x=5 now for getting y to equal a number instead of an equation 3(5)+7y=-6 15+7y=-6 subtract 15 on both sides to get 7y=-21 not divide by 7 on both sides to get y=-3 your answers are y=-3 and x=5

Answer:
.
Step-by-step explanation:
Start by finding the slope of this line.
If a slanting line goes through 
and 
, where 
, the slope of this line would be:
.
The line in this question goes through 
and 
. Hence, the slope of this line would be:
.
If a slanting line with a slope of 
and goes through the point , the equation of this line in the point-slope form would be:
.
For the line in this question, the slope is 
. Take as the chosen point on this line. The point-slope form equation of this line would be:
.
Rewrite to obtain the equation of this line in the slope-intercept form:
.
