Answer 2

• Distribute 1.2 to 6.3 and –7x.
• Combine 3.5 and 7.56.
• Subtract 11.06 from both sides.

Explanation:

We have the expression
`3.5 + 1.2(6.3 -7x) = 9.38`, we have to solve for x, and we are going to solve step by step.

1. We can distribute 1.2 to 6.3 and -7x, this is:

`3.5 + 1.2(6.3 -7x) = 9.38\\3.5+(1.2)*(6.3)+(1.2)*(-7x)=9.38\\3.5+7.56-8.4x=9.38`

2. We can combine 3.5 and 7.56

`3.5+7.56-8.4x=9.38\\11.06-8.4x=9.38`

3. We can subtract 11.06 from both sides of the equation:

`11.06-8.4x=9.38\\11.06-8.4x-11.06=9.38-11.06\\-8.4x=-1.68`

4. For the last step we are going to divide both sides in (-8.4):

`(-8.4x)/((-8.4))=(-1.68)/((-8.4)) \\\\x=0.2`

We obtain that x=0.2

And the steps we use from the list are:

• Distribute 1.2 to 6.3 and –7x.
• Combine 3.5 and 7.56.
• Subtract 11.06 from both sides.
