Answer:
x = -1.2
Step-by-step explanation:
Th given equation is :
34(x + 4) = 14(x + 8)
Step (A) Distribute 34 on the left side of the equation such as :
34x + 34(4) = 14(x + 8)
34x + 136 = 14(x + 8)
Step (B) Distribute 14 on the right side of the equation such as :
34x + 136 = 14x + 14(8)
34x + 136 = 14x + 112
Step (C) Subtract 14x from each side of the equation.
34x + 136 - 14x = 14x + 112 -14x
20x + 136 = 112
Step (D) Subtract 136 from each side of the equation.
20x + 136 -136 = 112 -136
20x = -24
Step (E) Divide both side by 20
![\dfrac{20x}{20}=\dfrac{-24}{20}\\\\x=-1.2](https://tex.z-dn.net/?f=%5Cdfrac%7B20x%7D%7B20%7D%3D%5Cdfrac%7B-24%7D%7B20%7D%5C%5C%5C%5Cx%3D-1.2)
So, the value of x is (-1.2). Hence, steps (D) and (E) are incorrect.
Answer:
-2x
Step-by-step explanation:
4x-6x=-2x. You need to combine like terms or subtract 6 from 4 which is -2 the you add then put the x back in
