3.6m − 2.7 = −1.8m

m = -2.7 / -5.4
m = 0.5
3t-1=8
3t=8+1
3t=9
3t divide by 9
Will give you 3
So your t value would be 3
Explanation: you would have to bring the -1 over to the 8, making the 1 positive. Then you would add up 8 nd 1.
And just divide the two numbers so 9 divide by 3. And you would have your answer T=
