Plsss help!!!!!

Answer 1

answer: x=3
work cited:
128(x+1)=512
distribute 128 into parenthesis
128x+128=512
subtract 128 and move it to the other side of parenthesis
128x=384
lastly divide the 128 from the x to the 384
128x/128=384/128
x=3

Answer 2

x=3

Explanation:

So first do distributive property, which makes it 128x+128=512, then subtract 128 from both sides which makes it 128x=384, then divide by 128 on both sides and you get x=3.
