What is the resulting equation when the expression for y in the second equation is substituted into the first equation? 3x y = 1
Natali5045456 [20]

After putting the value of y from the second equation to the first equation, the resultant equation is x=5.

GIven:

The equations are:

3x + y = 1\\&#10;y = 6 - 4x

It is required to put the value of y from second equation to the first equation.

<h3>How to solve equations?</h3>

The value of y from the second equation is,

&#10;y = 6 - 4x

Now, put this value of y in the first equation as,

3x + y = 1\\&#10;3x+(6 - 4x)=1\\&#10;3x+6-4x=1\\&#10;-x=-5\\&#10;x=5

Therefore, after putting the value of y from the second equation to the first equation, the resultant equation is x=5.

0.50x-6=4 this is algebra 1 can you please help me
horsena [70]

0.50x-6=4

move -6 to the other side

sign changes from -6 to 6

0.50x-6+6= 4+6

0.50x= 10

divide by 0.50 for both sides

0.50/0.50x= 10/0.50

x= 20

Answer: x= 20
