1. Tentukan nilai variabel dari persamaan-persamaaan di bawah ini.
a. 5(a+1) = 10
b. 0,5(4t-10) = 2(t+5)
c. 3(2z-1) + 1 = -2(2z+9)
d. -(4n-4) + 5n = 2n + 8
e. 20(3x+1) = -50(5-x)
f. 2c - 5(c-1) = 7 - 2c
g. 1/3 (6s-9) = 1/4 (-2s + 4)
h. 2/3p - 4 = 1/4p + 8
i. -2 + 3w per 5 = 10 + 4w per 7
j. 2(2b-4) - 3b = 8 - 4(2-0,5b)
