Step-by-step explanation:
hope that helps
The factors of 28 are 1,2,4,7,14,28
The factors of 42 are 1,2,3,6,7,14,21,42
The factors of 70 are 1,2,5,7,10,14,35,70
14
70
1 * 70
5 * 14
7 * 10
42
1 * 42
3 * 14
7 * 6
28
1 * 28
2 * 14
7 * 4
pick the largest factor from 70 and check it they also work with the other two. 14 is the GCF.
x = 1
Step 1: Write equation
9 - 2x = 7x
Step 2: Solve for <em>x</em>
<u>Add 2x on both sides:</u> 9 = 9x
<u>Divide both sides by 9:</u> x = 1
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9 - 2(1) = 7(1)
9 - 2 = 7
7 = 7
X=2
Y=1
