3 - x = 2

Add x to each side of the equation:

3 = x + 2

Subtract 2 from each side:

1 = x

3x - 5 = 2y3/2X - 5/2 = y

3x-1 = 7 3x = 8X= 8/3 = 2+2/3

6x-3x =6 3x=6 so 6 divided by 3 = 2

You cannot solve it with two unknown values 'x' & 'y' . However, it can be rearranged to form a strasight line eq'n. Hence -3x -3y = -15 Cancel down by '3' Hence -x -y = -5 Multiply by '-1', Hence x + y = 5 Hence y = -x + 5 Is the straight line eq'n. It has a slope/gradient of '-1' ; the coefficient of 'x' It intercepts the y-axis at '5'. ; ( 0,5)

3x - 5 = 2y3/2X - 5/2 = y

3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6

3x-2 = 2x+3 3x-2x = 3+2 x = 5

5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4

3x-1 = 7 3x = 8X= 8/3 = 2+2/3

6x-3x =6 3x=6 so 6 divided by 3 = 2

7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1

x equals 4 over 35
