7+2y=15subtract 7 from each side of the equal sign2y=8divide each side by 2y=4
3x + 2y = 7
x+2y = 7 2y = -x+7 y = -0.5x+3.5
If: 3x+2y = 5x+2y = 7 which is the same as 7 = 7 = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtracting equations: x = 0 Therefore by substitution: x = 0 and y = 3.5
3x-2y-7=0
7+2y=15subtract 7 from each side of the equal sign2y=8divide each side by 2y=4
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
3x + 2y = 7
x+2y = 7 2y = -x+7 y = -0.5x+3.5
It is 2y + 22 = 2(y + 11)
If: 3x+2y = 5x+2y = 7 which is the same as 7 = 7 = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtracting equations: x = 0 Therefore by substitution: x = 0 and y = 3.5
3x-2y-7=0
3x = 2y + 7 The standard form is: 3x - 2y - 7 = 0
If: 3x+2y = 5x+2y = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtract the 1st equation from the 2nd equation: 2x = 0 or x = o By substitution: x = 0 and y = 3.5
Add the two equations: x + y - x + 2y = 8 + 7 ie 3y = 15 so y = 5 making x = 3.
2y-7 = 14y+29 2y = 14y + 36 -12y = 36 -y = 3 y = -3
Sum Numb!
