1.
3(4v - 1) = 10
12v - 3 = 10
12v = 10 + 3
12v = 13
[tex]v=\frac{13}{12}[/tex]
2.
-5(-2t - 2) = -4
10t + 10 = -4
10t = -4 - 10
10t = -14
[tex]t=-\frac{7}{5}[/tex]
3.
-4(7m - 3) = -1
-28m + 12 = -1
-28m = -1 - 12
-28m = -13
[tex]m=\frac{13}{28}[/tex]
4.
6(2y + 2) = 4
12y + 12 = 4
12y = 4 - 12
12y = -8
[tex]y=-\frac{2}{3}[/tex]
5.
-3(-2 + j) = -8
6 - 3j = -8
-3j = -8 - 6
-3j = -14
[tex]j=\frac{14}{3}[/tex]
