I’m completely lost can i get the dedetails on how to do it on a piece of paper

Start by distributing 2 inside the parentheses holding 3b + 1. After distributing you will have: 12b + 9 = 6b + 9 + 6b + 2.

Now combine like terms on the right side of the equation, and after doing so you will have: 12b + 9 = 12b + 11.

Subtract 12b from both sides and now you have a weird looking equation (no variable!): 9 = 11.

Determine if this is a true or false statement; 9 = 11 is a false statement so that means that your answer is No solution.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
