-4 is the answer for x + 1 over 6 and x + 2 over 4.

(x+1)/6=(x+2)/4

(x+1)/3=(x+2)/2

2*(x+1)/3=x+2

2x+2=3(x+2)

2x+2=3x+6

3x-2x=2-6

x=-4.

(x+1)/6=(x+2)/4

(x+1)/3=(x+2)/2

2*(x+1)/3=x+2

2x+2=3(x+2)

2x+2=3x+6

3x-2x=2-6

x=-4.

Solve the linear equation.
-2x - 2 + 7(x + 1) = 2x - 4 **Weegy:**
-2x - 2 + 7(x + 1) = 2x - 4;
-2x - 2 + 7x + 7 = 2x - 4;
5x + 5 = 2x - 4;
5x - 2x = -4 - 5;
3x = -9;
x = -9/3;
x = -3
**User:** Solve and check the linear equation.

6x - 7 + 3(x + 1) = 4x - 6;

6x - 7 + 3x + 3 = 4x - 6;

9x - 4 = 4x - 6;

9x - 4x = -6 + 4;

5x = -2;

x = -2/5

6x - 7 + 3x + 3 = 4x - 6;

9x - 4 = 4x - 6;

9x - 4x = -6 + 4;

5x = -2;

x = -2/5

Solve the following system of equations, using the graphing method: y = 4 - 2x y = 7 - 3x
**Weegy:** Solve the following system of equations, using the graphing method: y = 4 - 2x y = 7 - 3x ?
Answer:
The addition method of solving systems of equations is also called the method of elimination. [ This method is similar to the method you probably learned for solving simple equations. You just need to add those equations but note that at least one of the coefficients of the 2 variables should be the same , or else multiply with suitable numbers to make it same.
3.
3x - 4y = -30
+ 7x + 4y = 10
- - - - - - - - - -
10x = -20
x = 20/10 = -2 and then subst. this in any of the equations to get the value of y .

The answer for y = 4 - 2x , y = 7 - 3x is x = 3 ,y = -2 .

put 1th equation in the 2th equation, we can get :

4-2x = 7 - 3x

4-7 = -3x + 2x

-3 = -x

x = 3,

y = 4 - 2x

y = 4 - 2*3

y = -2

put 1th equation in the 2th equation, we can get :

4-2x = 7 - 3x

4-7 = -3x + 2x

-3 = -x

x = 3,

y = 4 - 2x

y = 4 - 2*3

y = -2

The solutions for the systems x + 2y = 4, 2x - y = 3 are x = 2, y = 1.

Multiply x + 2y = 4 by -2:

-2x - 4y = -8;

(-2x - 4y = -8) + (2x - y = 3):

-5y = -5;

y = 1;

Solve for x:

x + 2(1) = 4;

x + 2 = 4;

x = 4 - 2;

x = 2

Multiply x + 2y = 4 by -2:

-2x - 4y = -8;

(-2x - 4y = -8) + (2x - y = 3):

-5y = -5;

y = 1;

Solve for x:

x + 2(1) = 4;

x + 2 = 4;

x = 4 - 2;

x = 2
