If you're asking what x equals, it equals 5 because 5x3=15, and 15-2=13.
In the equation 3x plus 7 equals 13, x is equal to 2.
y = (13 - 3x)/2 and that cannot be simplified further.
3x + 2y = 13Subtract 3x from each side:2y = -3x + 13Divide each side by 2:y = (-3/2)x + (13/2)The graph is a straight line, with a slope of (-3/2),through the point (0, 13/2) .
3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
3x - 2 + 5 = 16 3x + 3 = 16 3x = 13 x = 13/3 ~ 4.333
In the equation 3x plus 7 equals 13, x is equal to 2.
2x+3y=13 3x-y=3 x=2
y = (13 - 3x)/2 and that cannot be simplified further.
3x = 39 x = 13
4x - y = 1 3x + y = 13 Simultaneous Equations. Add ; This will eliminate 'y' Hence 7x = 14 x = 2 When x = 2 3(2) + y = 13 6 + y = 13 y = 13 - 6 y = 7 Hence the solution in ( x,y) form is ( 2, 7).
13-3x = 43 -3x = 43-13 -3x = 30 x = -10
3x + 2y = 13Subtract 3x from each side:2y = -3x + 13Divide each side by 2:y = (-3/2)x + (13/2)The graph is a straight line, with a slope of (-3/2),through the point (0, 13/2) .
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
X = -2(13 + y) / 3x = 5y / 4 - 1
Answer: Between integers 6 and 7Math:5x = 3x + 135x -3x = 3x -3x + 132x = 13(2x) : 2 = (13) : 2Int (6) < (x = 6.5) < Int (7)
3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13
