If you mean: 3x-4y = 19 and 3x-6y = 15 Then: x = 9 and y = 2
You can write this as two equations, and solve them separately. The two equations are:x - 19 = -3and:-x - 19 = -3

Let's call the two numbers x and y. We can set up a system of equations based on the given information: x + y = 51 and x - y = 13. By solving this system simultaneously, we can find the values of x and y. Adding the two equations together, we get 2x = 64, so x = 32. Substituting x back into the first equation, we find that y = 19. Therefore, the two numbers are 32 and 19.
= -1 + 5x
Solution: 19 and 12. 19 + 12 = 31 19 - 12 = 7 Solve using subsitution or simultaneous equations.
Let's denote the two numbers as x and y. We can set up a system of equations based on the given information: x - y = 19 and xy = 1170. By solving this system of equations, we find that the two numbers are 39 and 20.
Let the two numbers be ( x ) and ( y ). We can set up the equations: ( x + y = 19 ) and ( x - y = 9 ). By solving these equations, we can add them to eliminate ( y ): ( (x + y) + (x - y) = 19 + 9 ) gives ( 2x = 28 ), resulting in ( x = 14 ). Substituting ( x ) back into the first equation, ( 14 + y = 19 ), we find ( y = 5 ). Thus, the two numbers are 14 and 5.
First, add 19 on both sides. You end up with 2s = 48. Then divide both sides by 2 in order to isolate the 's'. You get s = 24.
4x + 3 = 11 6x - 9 = 3 17y +4 = 21 8y - 19 = -11
Linear equations have a variable only to the first degree(something to the power of 1). For example: 2x + 1 = 5 , 4y - 95 = 3y are linear equations. Non-linear equation have a variable that has a second degree or greater. For example: x2 + 3 = 19, 3x3 - 10 = 14 are non-linear equations.
Equations: 2x-3y = 4 and 5x+2y = 1 Multiply all terms in 1st equation by 5 and all terms in 2nd equation by 2:- So: 10x-15y = 20 and 10x+4y = 2 Subtract the 2nd equation from the 1st equation: -19y = 18 => y = -18/19 By substitution the solutions are: x = 11/19 and y = -18/19
