3x + 10x - 48 = 0 13x = 48 x = 3.692307692
3x+12=x+48: 3x-x=-12+48 2x=36 x=18
really depends. 12x - 8y = 48 3x - 2y = 12. You can't decide, but one ordered pair is (4,0)
2x+3x = 5x
If: 3x = 15 Then: x = 5
3x+5y=48 5y=48-3x-3x+5y=12 -3x+(48-3x)=12-6x=-36x=65y=48-3(6)5y=30y=6(6,6)
3x + 10x - 48 = 0 13x = 48 x = 3.692307692
3x+12=x+48: 3x-x=-12+48 2x=36 x=18
3x - 5 = 48 So 3x = 53 and x = 53/3 = 17.66...
x=4 or x=-4
If: 3x = 48 Then: x = 16
This is elementary stuff: 3x + 6 = 54 Subtract 6 from each side: 3x = 48 Divide each side by 3: x = 16.
Algebraically, 3X = 16 X = 16/3 ------------check in original equation 3(16/3) = 16 3, top and bottom cancel, so 16 = 16 ----------------checks
3x + 13 = 61 - 3x : add 3x to both sides 6x + 13 = 61 : deduct 13 from both sides 6x = 48 : divide both sides by 6 x = 8
48 = 144
3x-2y=24 (1)6x-4y=-6 (2)(1) => 6x-4y=48 [(1)*2](1)*2=(2)therefore:6x-4y = -6 AND 48-6 ≠ 48the equation cannot be solved
really depends. 12x - 8y = 48 3x - 2y = 12. You can't decide, but one ordered pair is (4,0)
