Using the two equations above, solve for x.

Question

2x =2y + 40

3y =48 - 9x

 

Using the two equations above, solve for x.

 

A. 

x = 64

B. 

x = 8

C. 

x = -11

D. 

x = 9

 

Answer 1

You can solve this.  From the first equation, after dividing all of it by 2,you have an expression x = something.

Substitute that for x, in the second equation. That will give you a numerical value for y.

Finally, substitute that in the first equation, thus finding what x is.
