Answer:
0.12x+0.15 (13-0.2x) = 0.69
0.12x +1.95 -0.26x = 0.69
-0.14x +1.95 -0.69 = 0
-0.14x +1.26 = 0
0.14x = 1.26
14/10 x = 126/10
x = 126/14
x = 9

Answer:
x=-5.81/0.22
Step-by-step explanation:
0.4x+0.5[(13-0.2x)/0.3]=2.3
0.4x+(6.5-0.1x)/0.3=2.3
0.12x+6.5+0.1x=2.3(0.3)
0.22x+6.5=0.69
0.22x=0.69-6.5
0.22x=-5.81
x=-5.81/0.22
