Four times a number, x, plus 3 times a number, y, equals 75. Five times x minus 3 times y equals 6. Find the numbers by setting up a system of linear equations and solving the system using the elimination method. x = -7, y = 12

x = 6, y = 14

x = 8, y= 11

x = 9, y = 13

Point Form:

( 9 ,  13 )  

Equation Form:

x  =  9 ,  y  =  13

Step-by-step explanation:

4x + 3y = 75 , 5x - 3y = 6

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

c
