3x + 2y = 8 This is an equation. It could be the equation of a line.
2x+3y=12 ......1st equation 3x+2y=13 .......2nd equation ____________________________________ multiplying 1stt equation by 3 and 2nd equation by 2 3x(2x+3y=12) 2x(3x+2y=13) _______________________________ now the equations become 6x+9y=36 ...3rd 6x+4y=26 ....4th by solving both equation(substractinf 4th from 3rd) we get.. 5y=10 therefore y=2 and x=3
3X + 6 = 12 subtract 6 from each side 3X + 6 - 6 = 12 - 6 3X = 6 divide each sides integer by 3 (3/3)X = 6/3 X = 2 ------------check in original equation 3(2) + 6 = 12 6 + 6 = 12 12 = 12 checks
Not until it equals something. Equations have equals signs.
y = 12. It's the transitive property. y = 12 = 3x.
Point slope equation: Y=3X+12
If: 3x+6 = 12 Then: x = 2
15
y=3x+12
12/3 = 4
12
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
x = 12 and y = 8
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
It is an equation and the value of x is 12
X = 12
