Yes get into it girl you right oh ya so right
Answer:
x=-3, y=-19
Step-by-step explanation:
we can solve by substitution.
y = 2x-1 we can derive from the second equation.
plugging it into the first equation, 2x -3(2x-1) = 15.
simplying, 2x-6x+3 = 15 --> -4x+3 = 15, -4x = 12, x = -3.
now we know x, so we can solve for y by plugging it into one of the equations. --> -3*-6+y = -1
simplify, 18+y = -1 --> y = -19.
The equation given above is,
3x - 4y = 2
This can be expressed in slope-intercept form by transposing y to one side of the equation,
y = (2 - 3x) / -4
Simplifying,
y = 3x/4 - 1/2
The equations will form a system with no solution only if they have the same slope but different y-intercept.
(1) 2y = 1.5x - 2
y = 3x/4 - 1
Since this has the same slope as the given equation but different intercept then, this is one of the answers.
(2) 2y = 1.5x - 1
y = 3x/4 - 0.5
This is exactly the same as the given equation then, the equations will have infinite number of solutions.
(3) 3x + 4y = 2
4y = (2 - 3x)
y = -3x/4 - 1/2
The equations do not have the same slope so, this is not one of the answers.
(4) -4y + 3x = -2
y = (-3x - 2) / -4
y = 3x/4 - 1/2
This equation is also exactly as that which is given. Hence, they will have infinite number of solutions.
