Answer: 1. A 2. 1/5 3. 5/12 4. Not sure
Step-by-step explanation:
-5 (2u+10)=2 (u_7) apply distributive property
-10u-50=2u-14 collect like terms
-10u-2u=50-14 when you move the number to the other side sign change
-12u =36 to get rid of 12 divide 12 on both sides
-12u/-12= 36/-12
U= -3
Your answer is B. I hope this is helpful!
