Answer:

X=20

Explanation:

Well you jsut gotta combine liek terms and sovle

I first made everything a common value since there are different denominators…

so

4/5=8/10

8/10x-3=3/10x+7

Now I’d clear both sides of any extra terms and combine them if possible

Theres a -3 and 7 so I jsut added 3 on both sides to cancel out the 3 on the left side

8/10x=3/10x+10

Now I jsut multiply by 10/1 to clear out the fractions to make this equation a lot easier, and by doing that what I’m really doing is clearing the denomniator but you can’t forget to multiply everything by 10 so 10*10=100

8x=3x+100

Clear like terms by subtracting 3x on both sides

5x=100

Isolate the x by dividing 5 on both sides

which would turn out to be x=20.
