Answer:
Option B. 1.8(2x + 7) – 15 = 3.6x – 2.4
Step-by-step explanation:
1.8(2x + 7) – 15
To know which option is correct, let us simplify the above expression. This can be obtained as follow:
1.8(2x + 7) – 15
Clear bracket
1.8(2x + 7) – 15 = 3.6x + 12.6 – 15
1.8(2x + 7) – 15 = 3.6x – 2.4
Thus,
1.8(2x + 7) – 15 is equivalent to
3.6x – 2.4

Answer:
x = 6
Step-by-step explanation:
The parallel lines divide the sides proportionally. So, we can write the equation ...
x/4 = (x +3)/6
3x = 2(x +3) . . . . . multiply by 12
x = 6 . . . . . . . . . . . subtract 2x
