The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
y=4 x+y=5 so it wud be:::::: x+4=5 solve it from there by doing 1 step equation :)
I assume that you mean 5x + y = -5 -4x + 2y = 2 Cancel the 2s from the second equation -2x + y = 1 therefore y = 1+2x Substitute into first equation 5x + 1 + 2x = -5 7x = -6 x = -6/7 Substitute into second equation to find that y = -5/7.
To check this, you substitute the values for x and y into the equation. At (1,2) x equals 1 and y equals 2 so substituting this in we get: x + 2y = 1 + 2(2) = 1 + 4 = 5 And since it equals 5 like in the original equation the point is represented by it.
A quadratic equation.

Answer is 411 Logic: You multiply the two numbers in LHS of the equation and reverse the result to form the first two digits of RHS and for the 3rd digit you subtract one from the 2nd number on the LHS of the equation.

2x + y = 25 x + y = 14 Subtract second equation from the first: x = 11 Substitute this value of x in the second equation: 11 + y = 14 ie y = 3
I assume that you mean 5x + y = -5 -4x + 2y = 2 Cancel the 2s from the second equation -2x + y = 1 therefore y = 1+2x Substitute into first equation 5x + 1 + 2x = -5 7x = -6 x = -6/7 Substitute into second equation to find that y = -5/7.
Substitute y = 0 in the equation: 0 = 3x + 7 so that x = -7/3
2x+y = 10 x +y = 4 Subtract bottom equation from top equation: x = 6 Substitute the value of x into the equations to find the value of y: x = 6 and y = -2

A quadratic equation.
That's the equation.
x = 0 and y = 4
2x+5 = 62 and 3x-y = 23.3 x = 28.5 and y = 62.2 Solve the first equation and then substitute the value of x into the second equation to find the value of y.
