Question 345054
Hi,
You are absolutely correct to start with multiplying each side of the equation by 9!!

{{{9*70= 5(F-32)}}}
.
Distribute the "5" to simplify:
{{{9*70= 5*F-5*32}}}
.
Simplify:
{{{630= 5*F-160}}}
.
combine like terms (Add 160 to both sidees of the equation)
{{{630+160= 5*F}}}
{{{790= 5*F}}}
.
{{{F=highlight(158)}}}
