<span>7x - 5 = 2
add 5 to both sides
</span><span>7x - 5+5 = 2+5
7x=7
Divide both sides by 7 to get x by itself
x=1 </span>
It is also the geometric mean of 4
Answer:
Her final answer should have been x = 1/2.
Step-by-step explanation:
Her 2 errors were that she didn't distribute the 2x to both 4 and -17 and that she made the 13 positive instead of negative when she added 4 and -17 together.
Correct solution:
8(x-3)+7=2x(4-17)
8x-24+7=8x-34x
-17=-34x
The negatives on both sides cancel each other out
x = 1/2
