Answer:
pls mark me brainliest
Step-by-step explanation:
X=1 y=2.5 I’m not sure if that’s correct but I hope it is.
7(3a + 12) = 168 ← ( divide both sides by 7 )
3a + 12 = 24 ← ( subtract 12 from both sides )
3a = 12 ← ( divide both sides by 3 )
a = 4
OR
distribute the parenthesis by 7
21a + 84 = 168 ← ( subtract 84 from both sides )
21a = 84 ← ( divide both sides by 21 )
a = 4
Hello there, and thank you for posting your question here on brainly.
To find this, you have to find the greatest common factor. (GCF)
GCF = 3
<span>Factor out the GCF: Write the GCF first. Then, in parentheses, divide each term by the GCF.

3 (15t/3 + 6/3)
Simplify.
-3(5t + 2)
Hope this helped! ☺♥
