-7r+13=-71

move 13 to the other side

sign changes from +13 to -13

-7r+13-13= -71-13

-7r= -84

divide both sides by -7 to get r by itself

-7r/-7= -84/-7

Answer: r= 12

Solve for x in the second equation.

Just add 1 to both sides to get x = 9y + 1

Then plug 9y + 1 into the first equation for x

7(9y+1) - 9y = 1

63y + 7 - 9y = 1

54y + 7 = 1

54y = -6

y = -6/54 or -1/9

Plug y back into one of the equations to get x = 0

Answer: (0, -1/9)
