Question

Find the value of x for the given simultaneous equation using camers rule x-2y=1; 5x+2y=29​

Answer 1

Answer:

Solve this system of simultaneous equations:

1) 3x + 4y = 19

2) 2x − y = 9

Solution. If we add the equations as they are, neither one of the unknowns will cancel. Now, if the coefficient of y in equation 2) were −4, then the y's would cancel. Therefore we will expand our strategy as follows:

Make one pair of coefficients negatives of one another -- by multiplying

both sides of an equation by the same number. Upon adding the equations, that unknown will be eliminated.

To make the coefficients of the y's 4 and −4, we will multiply both sides of equation 2)

Hope this helps you☺
