To solve the system of equations, which expression could be substituted for x into the first equation?

3x-5y=14
x+4y=10

a)10-4y
b)4y+10
c)(1/4)x+(5/2)
d)(-1/4)x+(5/2)

I have another problem just like this one so if you could explain how to solve this one I can (hopefully) solve the other,thanks

Solve the second equation for x:

x + 4 y = 10 --->

x = 10 - 4 y

ok I think I got the idea,lets try this one.

2x+7y=10
x-2y=15

I'm thinking 2y-15 here are the choices:
a)(1/2)x+15
b)(1/2)x-15
c)2y+15
d)2y-15

x-2y=15 ---->

x = 2y + 15

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to x from the first equation is substituted into the second equation. x – 2y = 2 x + 3y = 17

Solve the system of equations with ROWOPS program. I know how to do the first step but after that it gets difficult for me, this is the system of equations: 3x + y - z = 1 x + 2y - z = 0 2x - y + z = 4 I used to be able to do

How do you solve system of equations and tell if they're consistant and independant,consistant and dependent,and inconsistant? If you find no solutions then the system is inconsistent. Suppose you have N variables and M equations
