WILL GIVE BRAINLIEST TO 1ST<br> 4x+188=6x+216
Ulleksa [173]

Answer:

x = -14

Step-by-step explanation:

Let's solve your equation step-by-step.

4x + 188 = 6x +216

Subtract 6x from both sides:

4x + 188 - 6x = 6x + 216 - 6x

-2x + 188 = 216

Subtract 188 from both sides:

-2x + 188 - 188 = 216 - 188

-2x = 28

Divide both sides by two:

\frac{-2x}{-2}=\frac{28}{-2}

x = -14
