7c + 7a - 7r + 8m + 2y=31

solve for c a r m and y

For this case we have the following equation:

We solve for c:

We pass the terms that do not contain "c" to the other side of the equation by changing signs:

We divide by 7 on both sides of the equation:

We solve for "a":

We pass the terms that do not contain "a" to the other side of the equation by changing signs:

We divide by 7 on both sides of the equation:

We solve for r:

We pass the terms that do not contain "r" to the other side of the equation by changing signs:

We multiply by -1 on both sides:

We divide by 7 on both sides of the equation:

We solve for m:

We pass the terms that do not contain "m" to the other side of the equation by changing signs:

We divide by 7 on both sides of the equation:

We solve for y:

We pass the terms that do not contain "y" to the other side of the equation by changing signs:

We divide by 2 on both sides of the equation:

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
