Answer:
x=12
Step-by-step explanation:

Now, we can solve fore X! We can combine 35 and 7 to make the equation 
. In order to isolate x we have to subtract 42 from both sides, getting us the equation 
Now, in order to isolate x we must divide each side by 4, getting us the equation 
. To prove that x=12, we can subsitute x for 12. This means that we can do 
which simplified, is 90=90, making x=12 true. Hope this helps :)
