What are the solutions to the simultaneous equations of 7x plus 4y equals 9 and 2x plus 3y equals 1 in step by step stages?
Equations: 7x+4y = 9 and 2x+3y = 1
Multiply all terms in the 1st equation by 2 and all terms in the 2nd equation by 7
So: 14x+8y = 18 and 14x+21y = 7
Subtract the 1st equation from the 2nd equation: 13y = -11 => y = -11/13
By substituting y = -11/13 into any of the equations x = 23/13
Therefore the solutions are: x = 23/13 and y = -11/13

What is second version of the five stages in of man?
The second version of the five stages of man often refers to the "five stages of grief," which were introduced by Elisabeth Kübler-Ross. These stages are denial, anger, bargaining, depression, and acceptance, representing the emotional responses individuals may experience when dealing with loss or trauma. This model highlights the non-linear nature of grief, as people may move back and forth between stages rather than following a strict progression.

What are the solutions to the simultaneous equations of 6.6x plus 16.5y equals 52.8 and -16.5x -6.6y equals 6.6 showing key stages of work?
Eqn (A): => 2x + 5y = 16 Eqn (B): => 5x + 2y = -2 5*Eqn (A) - 2*Eqn (B): 21y = 84 => y = 4 Substituting for y in Eqn (a): x = -2
How do you find the solutions of the simultaneous equations of 2x plus 5y equals 16 and -5x-2y equals 2 showing work in step by step stages?
1 If: 2x+5y = 16 and -5x-2y = 2 2 Then: 2*(2x+5y =16) and 5*(-5x-2y = 2) is equvalent to the above equations 3 Thus: 4x+10y = 32 and -25x-10y = 10 4 Adding both equations: -21x = 42 or x = -2 5 Solutions by substitution: x = -2 and y = 4
