Q: Solve the following system of equations, using the elimination method:
x + 6y = 79
x - 4y = - 41

A: Move the center x to the left in order for x to eliminate. Then, move 4y to the left resulting the equation to become 6y + 4y = -41;
10y = -41;
Then, divide both sides with the value of 10 in order to get the value of y. 10/10y = -41/10;
y= -4.1

-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

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

The solution set for the systems x + 2y = 4, 2x - y = 3 is: (2, 1)

(x + 2y = 4) * (-2);

-2x - 4y = -8;

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

-5y = -5;

y = 1;

x + 2 = 4;

x = 4 - 2;

x = 2

(x + 2y = 4) * (-2);

-2x - 4y = -8;

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

-5y = -5;

y = 1;

x + 2 = 4;

x = 4 - 2;

x = 2
