Question

What is the value of x if
2x + 5 = 19 ? ASAP

Answer 1

2x+5=19

2x=19-5

x=14/2

x=7

Answer 2

`\large \boxed{x = 7}`

Explanation:

Goal

• Solve for x-term.

Given

• Equation

`2x + 5 = 19`

Step 1

• Isolate x by subtracting 5 both sides.

`2x + 5 - 5 = 19 - 5 \\ 2x + 0 = 14 \\ 2x = 14`

Step 2

• Divide both sides by 2 to make only x-term as our subject.

`(2)/(2) x = (14)/(2) \\ (1)/(1) x = 7 \\ 1x = 7 \\ x = 7`

Step 3 (Optional)

• If you are not sure that the answer is correct or not, we can check the answer by substituting x = 7 in the equation.

`2x + 5 = 19`

Substitute x = 7 in the equation.

`2(7) + 5 = 19 \\ 14 + 5 = 19 \\ 19 = 19`

The equation is true for x = 7. Hence, the answer is x = 7.
