at a restaurant the cost for a breakfast taco and a small glass of milk is $2.10. The cost for 2 tacos and 3 small glasses of milk $5.15. Which pair of equations can be used to determine t, the cost...

i don't know how to do this I need help

how do i solve this?

if the equations are y=2x-5 and 4x-y=7 , what is the ordered pair ?

3x+7y=-6 x+6y+2=0 I have a problem when you have to move the equation and make it into one.

x=6+4y -3(x+y)=-36 I have to solve this using the system of equation by the substitution method.

5a+7b=-21 a+18=-6b I have a problem when you have to move the equation and make it into one.

how can written thousands equation simplified.
