Insert grouping symbols to make the answer correct. then evaluate the expression to justify your work. 9 + 3 • 4 - 6 + 12 / 3 = -20

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

is there any photos or whatever?
