A company sells trinkets and doodads. It costs the company $30 to make 4 trinkets and 2 doodads and $40 to make 3 trinkets and 4
vfiekz [6]
Tinkets:
4x = 30 \\ x = 7.5
now the next step
3x + 4y = 40
since you know x, you're able to substitute

3 \times (7.5) + 4y = 40 \\ 22.5 + 4y = 40 \\ 4y = 17.5 \\ y = 4.375
so trinket: $7.5
doodad: $4.375

If x+y=z and z=x+4,then x+y=x+4
lidiya [134]
That is true because as you can see in the other 2 equations, they both have z on one of the sides meaning that the sides that don't have z are equal to each other

Hope this helps :)
