Question

how many solutions does 5x - 4x = 2x + 6 have

Answer 1

Answer:

B. No solutions

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

7−4x=2+x+6−5x

7+−4x=2+x+6+−5x

−4x+7=(x+−5x)+(2+6)(Combine Like Terms)

−4x+7=−4x+8

−4x+7=−4x+8

Step 2: Add 4x to both sides.

−4x+7+4x=−4x+8+4x

7=8

Step 3: Subtract 7 from both sides.

7−7=8−7

0=1

Answer 2

Answer:

5x-4x+2x=6

We move all terms to the left:

5x-4x+2x-(6)=0

We add all the numbers together, and all the variables

3x-6=0

We move all terms containing x to the left, all other terms to the right

3x=6

x=6/3

x=2
