Answer:
x= y-10a/10
Step-by-step explanation:
Multiply 10 by x+a using the distributive property. 10x+10a=y
Subtract 10a from both sides. 10x=y-10a
Divide both sides by 10. 10x/10 = y-10a/10.
Dividing by 10 undoes the multiplication by 10. x=y-10a/10
Divide y-10a by 10.
I hope this helps and I'm sorry if I got this wrong. I tried my best. Thanks for the question :)
