$1 = $20.19 pesos, try dividing 510 pesos by 20.19. That should give you the dollar amount.
First you expand the brackets:
3x - 27 = 30
And then you can solve:
3x - 27 = 30
+ 27
3x = 57
÷ 3
x = 19
Hope this helps!
Answer:
Hey there!
Let x be the price of lipstick
Let 1/2x be the price of shampoo
1.5x=20
x=13.33
1/2x=6.67
The shampoo costed $6.67, and the lipstick costed $13.33
