Factorize the left hand side and equate the factors to zero.

Then, use the notation that : sec x = 1/cosx and csc x = 1/sinx

Result: x = ± π3 + 2πk , k∈Z

9x+5y=34 <br>8x-2y=-2<br>What are the values of x and y? Please explain the steps.

allsm [11]

Answer:

x = 1 and y =5

Step-by-step explanation:

$8x -2y= -2\\Divide by -2\\-4x+y = 1\\add 4x\\y= 1+4x\\$

Substitute this value of y in the next equation.

$9x+5(1+4x) = 34\\9x+5+20x=34\\29x+5=34\\29x=29\\x=1$

Solve for y using x.

$y=4x+1\\y=4(1)+1\\y=5$
