Verified Answer
Which is a solution of the equation 7x + 5 = 19?a)x = 2b)x = 3c)x = 4d...
Given equation is 7x + 5 = 19
7x = 19 - 5
7x = 14
Therefore, x = 2
So option A is the correct answer.

Which is a solution of the equation 7x + 5 = 19?a)x = 2b)x = 3c)x = 4d...
Solution:
We need to solve the equation 7x - 5 = 19 to find the value of x.
Step 1: Add 5 to both sides of the equation
7x - 5 + 5 = 19 + 5
Simplifying the equation, we get
7x = 24
Step 2: Divide both sides of the equation by 7
7x/7 = 24/7
Simplifying the equation, we get
x = 24/7
The value of x is not a whole number, so it is not one of the answer choices. However, we can approximate the value of x to the nearest whole number.
Step 3: Divide 24 by 7 using long division or a calculator
24 ÷ 7 = 3 remainder 3
Step 4: Add the remainder to the quotient to get the approximate value of x
x ≈ 3 + (3/7)
Therefore, the closest integer value of x is 3.
However, none of the answer choices match our approximation, so the correct answer is None of These.
Therefore, the given solution is incorrect.

Which is a solution of the equation 7x + 5 = 19?a)x = 2b)x = 3c)x = 4d...
It is because if 7 is multiplied by 2 and 5 is added only then we will get 19. Equation = 7(2) + 5 = 19
