Y=1/2x +5 Y=-3/2x-7 Find x and y

Mathematics

I'm going to use the substitution method. 

If y = - 3/2 - 7, then:

1/2x + 5 = - 3/2x - 7

Combine like terms: 

4/2x = - 12. Mutiply both sides by 2/4 to get x = -12 (2/4)

Simplify to get:

x = - 6.

Plug - 6 back in for x in either equation.

Y = 1/2( - 6) + 5 which becomes Y = - 3 + 5.

X = - 6, Y = 2

It's C
first keep C in one side and other in other side of equation like this:
9c/5= F-32
now multiply both side by 5 or do cross multiplication
then it becomes
9c=5(F-32)
now divide both side by 9
c=5/9(F-32)
