Question

4a) Solve each equation.

Answer 1

x = 6

Explanation:

Given equation,

→ 2x + 7 = 19

Now we have to,

→ Find the required value of x.

Then the value of x will be,

→ 2x + 7 = 19

Subtracting the RHS with 7:

→ 2x = 19 - 7

→ 2x = 12

Dividing RHS with number 2:

→ x = 12/2

→ [ x = 6 ]

Hence, the value of x is 6.

Answer 2

Answer: x = 6

Explanation:

To solve, we will isolate the x-variable.

Given:

2x + 7 = 19

Subtract 7 from both sides of the equation:

2x = 12

Divide both sides of the equation by 2:

x = 6
