Question

How do you solve for x using the problem above?

Answer 1

First you have to subtract 35 on both sides, then you would have to divide by 90

Answer 2

Step 1: Find the Greatest Common Factor (GCF)
1. What is the largest number that divides evenly into $90x$ and $35$? 5

2. What is the highest degree of $x$ that divides evenly into $90x$ and $35$? None, $x$ is not in every term

3. Multiplying the results above, the GCF is $5$

(The GCF is 5)

Step 2: Factor out the GCF 
1. Put the GCF as the first term
2.Then, in parentheses, divide each term by the GCF

$5( \frac{90x}{5} + \frac{35}{5})$

Step 3: Simplify each term in parentheses

$5(18x+7)$

Done! :)
