Question

Solve the system of equations for the smaller and larger numbers.

a) y = -x + 31
b) y = 2x + 7
c) y - 3x + 1
d) y - 2x + 7

Answer 1

To solve the system of equations, use the method of substitution and substitute each equation into the other three equations to find the values of x and y.

Step-by-step explanation:

To solve the system of equations, we will use the method of substitution:

a) y = -x + 31:

Substitute this equation into the other three equations to find the values of x and y.

b) y = 2x + 7:

Substitute this equation into the other three equations to find the values of x and y.

c) y - 3x + 1:

Substitute this equation into the other three equations to find the values of x and y.

d) y - 2x + 7:

Substitute this equation into the other three equations to find the values of x and y.
