Hi!
1.4t — 0.4 * t - 0.4 * —3.1 = 5.8
1.4t — 0.4t - 1.24 = 5.8
1t - 1.24 = 5.8
1t - 1.24 + 1.24 = 5.8 + 1.24
1t = 7.04
<u>t = 7.04</u>
Hope this helps! :)

1,4(0,5x + 4,2y) - 3,5(0,2x - 1,5y)
1,4.0,5x + 1,4.4,2y - 3,5.0,2x + 3,5.1,5y
0,7x + 5,88y - 0,7x + 5,25y
0,7x - 0,7x + 5,88y + 5,25y
11,13y
Answer: 3 hours
