Answer:

x = 0

Step-by-step explanation:

[tex]-8x-14=7(-2-4x)+4x\qquad\text{use the diastributive property}:\ a(b+c)=ab+ac\\\\-8x-14=(7)(-2)+(7)(-4x)+4x\\\\-8x-14=-14-28x+4x\qquad\text{add 14 to both sides}\\\\-8x-14+14=-14+14-24x\\\\-8x=-24x\qquad\text{add}\ 24x\ \text{to both sides}\\\\-8x+24x=-24x+24x\\\\16x=0\qquad\text{divdie btoh sides by 16}\\\\\dfrac{16x}{16}=\dfrac{0}{16}\\\\x=0[/tex]
