Find the ordered pair of x=5y-7 and x+5y=8

The desired ordered pair is (1/2, 3/2).

Step-by-step explanation:

Let's use the substitution method here to determine either x or y first:

x = 5y - 7 (given).  Then 5y - 7 can be substituted for x in x + 5y = 8:

5y - 7 + 5y = 8.

Combining like terms, we get 10y = 15, so that y = 3/2.

Find x by substituting 3/2 for y in x = 5y - 7:  x = 5(3/2) - 7 = 15/2 - 14/2 = 1/2

The desired ordered pair is (1/2, 3/2).

A is the answer

Step-by-step explanation:

5 multiplys by a to get 5a and 5 muliplys by b to get 5b

because a is equal to 1 and b is equal to 1

it applies to any letter

so 5*a= 5a

and 5*b=5b

so it turns into 5a+5b
