Given:

The given equations are
-6 x+4 y=22 and
y=11-4 x

We need to determine the pair of numbers that is a member to the system of equations.

Pair of numbers:

The pair of numbers can be determined by solving the system of equations.

Let us use the substitution method to solve the equations.

Substituting
y=11-4 x in the equation
-6 x+4 y=22, we have;


-6 x+4 (11-4x)=22


-6 x+44-16x=22


44-22x=22


-22x=-22


x=1

Thus, the value of x is 1.

Substituting x = 1 in the equation
y=11-4 x, we get;


y=11-4(1)


y=11-4


y=7

Thus, the value of y is 7.

Hence, the pair of numbers that is a member of both the equations are (1,7)
