Math Problem Statement

Determine if the ordered pair is a solution to the system of equations. -6x+4y=-8 4x+2y=24 (a) (4,4) (b) (6,7/6) The ordered pair (6,7/6) is or is not a solution to the system of equations

Solution

To determine if the ordered pair (6,76)(6, \frac{7}{6}) is a solution to the system of equations, we substitute x=6x = 6 and y=76y = \frac{7}{6} into both equations and check if they satisfy them.

The system of equations is:

  1. 6x+4y=8-6x + 4y = -8
  2. 4x+2y=244x + 2y = 24

Step 1: Substituting into the first equation

6(6)+4(76)=8-6(6) + 4\left(\frac{7}{6}\right) = -8 36+286=8-36 + \frac{28}{6} = -8 Simplify 286\frac{28}{6} to 143\frac{14}{3}: 36+143=8-36 + \frac{14}{3} = -8 Convert 36-36 to have a denominator of 3: 1083+143=943\frac{-108}{3} + \frac{14}{3} = \frac{-94}{3} 9438\frac{-94}{3} \neq -8 Thus, (6,76)(6, \frac{7}{6}) does not satisfy the first equation.


Step 2: Substituting into the second equation

4(6)+2(76)=244(6) + 2\left(\frac{7}{6}\right) = 24 24+146=2424 + \frac{14}{6} = 24 Simplify 146\frac{14}{6} to 73\frac{7}{3}: 24+73=2424 + \frac{7}{3} = 24 Convert 24 to have a denominator of 3: 723+73=793\frac{72}{3} + \frac{7}{3} = \frac{79}{3} 79324\frac{79}{3} \neq 24 Thus, (6,76)(6, \frac{7}{6}) does not satisfy the second equation.


Final Answer:

The ordered pair (6,76)(6, \frac{7}{6}) is not a solution to the system of equations.
