∙ 2009-12-14 00:36:36The 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 :)
A quadratic equation.
That's the 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.

The equation soild plus gas equals a liquid
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.

A quadratic 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
Substitute y = 0 in the equation: 0 = 3x + 7 so that x = -7/3
Iron plus chlorine equals Iron chloride is the word equation.
That's the equation.

oh- plus 2h+ equals 2h2o is the net ionic equation.
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
