Question

If 7x + 4 = -19 + 5x, then 2x – 14 equals
A-23
B 23
C-37
D-14​

Answer 1

To find the value of 2x - 14, we need to solve the given equation. The expression 2x - 14 equals -37.

Step-by-step explanation:

To find the value of 2x - 14, we need to solve the given equation.

Step 1: Start by combining like terms on both sides of the equation.

7x + 4 = -19 + 5x

Step 2: Subtract 5x from both sides to isolate the x-terms on one side.

7x - 5x + 4 = -19

2x + 4 = -19

Step 3: Subtract 4 from both sides.

2x + 4 - 4 = -19 - 4

2x = -23

Step 4: Divide both sides by 2 to solve for x.

2x/2 = -23/2

x = -23/2

Step 5: Finally, substitute the value of x into the expression 2x - 14.

2(-23/2) - 14 = -23 - 14 = -37

Therefore, 2x - 14 equals option C: -37.

Answer 2

C

Step-by-step explanation:

Here we have the question,

7x+4 = -19 + 5x

Now we add 19 to both sides,

7x + 4 + 19 = -19 + 19 + 5x

7x + 23 = 5x

Now we subtract 7x from both sides,

23 = -2x

We divide -2 from both sides,

x = -23/2

Now we plug this in into 2x - 14,

2(-23/2) - 14 = -23-14 = -37

Our answer is C
