Solve the following for the x and y values. X being 0 when solving for Y, and vice versa.
Aleonysh [2.5K]
It states your "X" will be zero when solving for "Y". So when solving for "Y" your equation would be; 0+y=4 Then you solve. Y=4 Then you do the same with the "X": X+0=4. Then you solve. X=4 It would end up being (4(x),4(y) ) Then do the same for the next problem.

Can anybody help me with understanding how to do -2+a/3 = -4?
Amanda [17]

Answer:

a = -14

Step-by-step explanation:

a-2/3=-4. Multiply -4 by 3 to get rid of the denominator. This leaves you with a-2 = -12. Move the -2 to the other side to get a = -2-12, which simplifies to a = -14.
