Therefore, y = 4

7 + 2y = 15

7-7 + 2y = 15-7 Subtract 7 from both sides

2y = 8 Divide by 2 to get y alone

2y/2 = 8/2

y = 4

Q: 7 plus 2y equals 15

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

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.
