Yes it is, since it can be represented in the form y = mx + b
12-3y = 15 -3y = 15-12 -3y = 3 y = -1
(5, 1)
Presumably this is a simultaneous equation in the form of: -4x+3y = 27 -2x+y = -1 Multiply all terms of the bottom equation by 2: -4x+3y = 27 -4x+2y = -2 Subtract the bottom equation from the top equation remembering that a - - is equal to a + Meaning that -4x - -4x = 0 and 27 - -2 = 29: So y will = 29 Substitute the value of y into the original equations to find the value of x Therefore: x = 15 and y = 29
{-1,-2}
-2x plus 3y equals 1
It's an hyperbola equation.
3y + 2y + 4 + 1 = 805y + 5 = 805y = 75y = 15
Multiply the bottom equation by -1
Multiply the top equation by 3 and the bottom equation by 2. (-4, 1)
second equation x 2: 4x + 6y = 4 subtract first equation: 9y = 3 so y = 1/3 and x = 1/2
Multiply first equation by 1.5, giving 3x + 3y = 12, but we are told that 3x + 3y = 6. If there isn't an error in the question then 2 = 1!
3y+2y+4+1=80 5y+5=80 5y=80-5 5y=75 y=15
2x plus 3y is not an equation, it is an expression.
The solution pair is (-7, 22), demonstrated as follows: (1) x + y = 15 : given; (2)4x + 3y = 38 : given; (3)3x + 3y = 45 : equation (1), multiplied by 3; (4) x = -7 : equation (2), minus equation (3); (5) y = 22 : equation (1), minus equation (4).
4x+3y = 3 3y = -4x+3 y = -4/3x+1 in slope intercept form
Yes it is, since it can be represented in the form y = mx + b
