7 0

Answer:

x=0;y=-2

Step-by-step explanation:

multiply first equation by 6: 18x-24y=48

Subtract 2nd equation from 1st: -19y=38

y=-2

Sub into 1st equation: 3x-4(-2)=8

3x+8=8

3x=0

Therefore, x=0;y=-2

Enter the value of x that makes the given equation true <br><br>12x = 3
anyanavicka [17]

Answer:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  12x - 3  =   3 • (4x - 1)  

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    4x-1 = 0  

Add  1  to both sides of the equation :  

                     4x = 1  

Divide both sides of the equation by 4:

                    x = 1/4 = 0.250  

One solution was found :

                  x = 1/4 = 0.250

How do i find the y-intercept of an eqaution that passes throught two points
Pachacha [2.7K]

They way to find the y-intercept from two points is to first find the slope, which can be derived from the formula m=\frac{y_2-y_1}{x_2-x_1}.

Then, you can plug in one of the two points (x_1,y_1) or (x_2,y_2) into the formula y=mx+b to solve for b, which is your y-intercept.
