4x + 5y = 2 and 7x - 2y = 1 From the first equation, x = (2 - 5y)/4 putting this value of x to the second equation, 7(2 - 5y)/4 - 2y =1 => (14 - 35y)/4 - 2y = 1 =>14 - 35y - 8y = 4 =>14 - 43y = 4 =>43y = 10 => y = 10/43 putting y = 10/43 in x = (2 - 5y)/4 => x =( 86 - 50 )/172 => x = 36/172 => x = 9/43 therefore, x = 9/43 and y = 10/43

How do you solve 0 equals x squared minus ten x plus 16?
Solve using the quadratic formula
How do you solve -x plus y equals 1 and -2 plus y equals -2 by substitution?
-x+y = 1 -2+y = -2 y = 1+x y = -2+2 => y = 0 By sustituting the values of x and y can be found x = -1 and y = 0 Remember that a minus from a minus is equal to a plus. So - -1+0 = 1
