Question and answer
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.

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 (More)

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

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

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
