Best Answer

x-2y=1 => x=2y+1 (1)

3x+y=-4 (2)

sub (1) into (2)

3(2y+1)+y=-4

6y+3+y = -4

7y+3 = -4

7y = -7

y = -1

sub back into (1)

x = 2(-1)+1

x = -2+1

x = -1

How do you write this equation 3x equals 2y plus 3 in function form?

3x = 2y + 3 3x -3 = 2y +3 -3 3x - 3 = 2y (3x -3)/2 = 2y / 2 y = 1/2 x (3x - 3) 3x = 2y +3 3x - 3x = -3x +2y +3 0 = -3x +2y +3 -1 x (0) = -1 x (-3x +2y +3) 0 = 3x - 2y -3

How do you write 3X equals 2Y plus 3 in function form?

3x = 2y + 3 3x -3 = 2y +3 -3 3x - 3 = 2y (3x -3)/2 = 2y / 2 y = 1/2 x (3x - 3) 3x = 2y +3 3x - 3x = -3x +2y +3 0 = -3x +2y +3 -1 x (0) = -1 x (-3x +2y +3) 0 = 3x - 2y -3

Simplify 3x plus 2y plus 2 equals 4y plus 4?

The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1

What is 3x plus 2y equals 1?

y=-3/2x + 1/2
