Resolva
x +2=5
2x-2y=2

Answer 1

Resposta:

x +2=5

Let's solve your equation step-by-step.

x+2=5

Step 1: Subtract 2 from both sides.

x+2−2=5−2

x+2+−2=5+−2

(x)+(2+−2)=(5+−2)(Combine Like Terms)

x=3

2x-2y=2

Let's solve for x.

2x−2y=2

Step 1: Add 2y to both sides.

2x−2y+2y=2+2y

2x=2y+2

Step 2: Divide both sides by 2.

2x/2=2y+2/2

x=y+1

Let's solve for y.

2x−2y=2

Step 1: Add -2x to both sides.

2x−2y+−2x=2+−2x

−2y=−2x+2

Step 2: Divide both sides by -2.

−2y/−2=−2x+2/−2

y=x−1

Answer 2

Resposta:

O valor correspondente a "x" é 3 e o valor correspondente a "y" é 2.

Desenvolvimento:

x + 2 = 5

x = 5 - 2

x = 3

2x - 2y = 2

2*(3) -2y = 2

6 - 2y = 2

- 2y = 2 - 6

- 2y = - 4

y = - 4/- 2

y = 2
