Arthur writes the equation a=10b−7

. He wants to rewrite it in terms of b
. In Arthur’s first step, what value should he add to both sides of the equation?(1 point)

1 answer

To rewrite the equation \( a = 10b - 7 \) in terms of \( b \), the first step is to isolate the term containing \( b \).

To do this, we can add \( 7 \) to both sides of the equation. This gives us:

\[ a + 7 = 10b \]

So, the value Arthur should add to both sides of the equation is \( 7 \).
