which statement is true about the equations –3x 4y = 12 and x1/4 – 1/3y = 1? the system of the equations has exactly one solutio
finlep [7]
If you would like to solve the system of equations, you can do this using the following steps:

-3x + 4y = 12
x * 1/4 - 1/3 * y = 1 ... x * 1/4 = 1 + 1/3 * y ... x = 4 + 4/3 * y
_____________
<span>-3x + 4y = 12
</span>-3 * (4 + 4/3 * y) + 4y = 12
-12 - 4y + 4y = 12
-12 = 12
-12 - 12 = 0
-24 = 0

The correct result would be: <span>the system of the equations has no solution; the two lines are parallel.</span>

Mice21 [21]

Answer:

x= -7/10 or x= -0.7 , y= 7

Step-by-step explanation:

Find the x-intercept:                  Find the y-intercept:

y= 5×2+10x-3                                y= 5×2+10x-3  

0=10+10x-3                                    y= 5×2+10×0-3

0=7+10x                                         y= 7

-10x=7

x=-7/10
