Question
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)

Answer 1

To rewrite the equation \( a = 10b - 7 \) in terms of \( b \), Arthur should first isolate the term that contains \( b \). To do this, he should add 7 to both sides of the equation.

Here's how it looks:

Starting with: \[ a = 10b - 7 \]

Adding 7 to both sides: \[ a + 7 = 10b \]

So, the value he should add to both sides of the equation is 7.
