What is one of the solutions to the following system of equations? y2 + x2 = 53
y − x = 5

x = 2 and y = 7

Step-by-step explanation:

The given equations are :

Squaring both sides of equation (2)

Put the value of y from equation (2)

Put the value of x in equation (2)

y-x = 5

y = 5+x

= 5+2

= 7

Hence, the solution of the given equations are (2,7).

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
