For an estimate, the closest is 210
First, you combine like terms. I would start by circling the term and the sign in front of it. (A term is a piece separated by an addition/subtraction sign.) You can only combine terms with the same variable. 4.8a-2.1a-6.3b+7b is the same as your equation, just rearranged. Then, subtract (4.8a-2.1a) which is 2.7a. Add (-6.3b to 7b) The answer is 0.7b.

Answer:
Step-by-step explanation:
you know that both angles=180
6x+20+2x+4=180
8x+24=180
8x=180-24
8x=156
x=19.5
angle TQS=19.5*60+20=137
angle SQR=2*19.5+4=43
