x=4
3+3x+7x=13 3x+7x=10 10x=10 x=1
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).
3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13
x equals -3, and y equals 1.
X = -2(13 + y) / 3x = 5y / 4 - 1
(2, -1)
y = 3x + 1
y = 3X - 1
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
If: 3x+5 = 4x+1 Then: x = 4
(1, 1)
x + 2 = 3x-1 -2x = -3x = 1,5
