2(-5a+7)=-a

First remove the parentheses by the distributive property:
-10a + 14 = -a

Next, you need to get the variable terms on one side (in this case preferably the right side by adding 10a to each side!):
-10a+%2B+10a+%2B+14+=+-1a+%2B+10a
14+=+9a

Finally, divide both sides by 9:
14%2F9+=+%289a%29%2F9+
14%2F9+=+a
