Answer:

(-1, 3)

Step-by-step explanation:

The given equation is 2x + y = 5.

Test whether (-1, 3) is a solution. To do this, substitute -1 for x and 3 for y. Does 2(-1) + 3 = 5? No, it does not. So this could be the correct answer choice.

Test whether (6, -7) is a solution. Is 2(6) - 7 = 5 true? Yes, it is. So this is not a correct choice.

Test whether (3, -1) is a solution. Is 2(3) -1 = 5? Yes, it is. So this is not a correct choice.

Summary: The only answer choice that does NOT satisfy the given equation is the first one: (-1, 3).

Solve 7r+ 2 = 5(r – 4)

AveGali [126]

Multiply the bracket by 5

I used PEMDAS

P= parenthesis

E= exponents

M=multiplication

D= division

A= addition

S= subtraction

7r+2= 5(r-4)

7r+2= 5r-20

Move 5r to the left hand side . Positive 5r changes to negative 5r

7r-5r+2= 5r-5r-20

2r+2=- 20

2r+2-2= -20-2

Move positive 2 to the right hand side. Changes to negative -2

2r+2-2= -20-2

2r= -22

Divide by 2 for 2r and -22

2r/2= -22/2

r= -11

Answer is r= -11
