Question and answer
7x - 3y = 4 2x - 4y = 1 The solution to the system of equations is _____. (13/34, -15/34), (3/22, -7/22), (13/22, 1/22).
7x - 3y = 4 multiple 4 on both sides; 28x - 12y = 16 (equation 1) 2x - 4y = 1 multiple 3 on both sides, 6x - 12y = 3 (equation 2) equation 1 - equation 2 the result is: 22x = 13, x = 13/22 7(13/22) - 3y = 4 (91/22) - 3y = 4 -3y = 4 - (91/22) = 88/22 - 91/22 = -3/22 y = (-3/22)/(-3) = 1/22 The solution for the system 7x - 3y = 4, 2x - 4y = 1 is (13/22, 1/22).

7x - 3y = 4 multiple 4 on both sides;
28x - 12y = 16 (equation 1)
2x - 4y = 1 multiple 3 on both sides,
6x - 12y = 3 (equation 2)
equation 1 - equation 2 the result is:
22x = 13,
x = 13/22
7(13/22) - 3y = 4
(91/22) - 3y = 4
-3y = 4 - (91/22) = 88/22 - 91/22 = -3/22
y = (-3/22)/(-3) = 1/22
The solution for the system 7x - 3y = 4, 2x - 4y = 1 is (13/22, 1/22).

Solve (4 - x = -1) n (2 + 3x = 17).
Weegy: 3(3x - 1) + 2(3 - x) = 0 9x - 3 + 6 - 2x = 0 9x - 2x + 3 = 0 7x = 0 - 3 7x = -3 x = -3/7 User: Solve (4 - x = -1) n (2 + 3x = 17). Weegy: hat depends on whether you mean (2/3)x or 2/(3x). will do them both For (2/3)x = 8, x = 8?(3/2) = 4?3 = 12 If you meant 2/(3x) = 8 then cross-multiply like this: 2 .... 8 - - = - - 3x ...1 2(1) = 8(3x) 2 = 24x so x = 2/24 = 1/12 (More)

4 - x = -1
-x = -1 - 4
-x = -5
x = 5;
2 + 3x = 17
3x = 17 - 2
3x = 15
x = 5.
The solution for (4 - x = -1) n (2 + 3x = 17) is x = 5
