Answer 2

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

7x - 5 = 17

Step 1: Add 5 to both sides of the equation.

⇒ 7x - 5 + 5 = 17 + 5

⇒ 7x = 22

Step 2: Divide 7 from both sides of the equation.

⇒ $\dfrac{7x}{7} = \dfrac{22}{7}$

⇒ $x = \dfrac{22}{7}$

∴ $\bf x = \dfrac{22}{7}$ in the equation → 7x - 5 = 17

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

2y - 5 = 7

Step 1: Add 5 to both sides of the equation.

⇒ 2y - 5 + 5 = 7 + 5

⇒ 2y = 12

Step 2: Divide 2 from both sides of the equation.

⇒ 2y ÷ 2 = 12 ÷ 2

⇒ y = 6

∴ y = 6 in the equation → 2y - 5 = 7

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

5 - 2y = 7

Step 1: Subtract 5 from both sides of the equation.

⇒ 5 - 2y - 5 = 7 - 5

⇒ -2y = 2

Step 2: Divide -2 from both sides of the equation.

⇒ $\dfrac{-2y}{-2} = \dfrac{2}{-2}$

⇒ y = -1

∴ y = -1 in the equation → 5 - 2y = 7
