Answer :
Answer:
x = 2
Step-by-step explanation:
Given
8(4 - x) = 7x + 2 ← distribute parenthesis on left side
32 - 8x = 7x + 2 ( subtract 7x from both sides )
32 - 15x = 2 ( subtract 32 from both sides )
- 15x = - 30 ( divide both sides by - 15 )
x = 2
Answer:
x = 2
Step-by-step explanation:
[tex]8(4-x)=7x+2\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\(8)(4)+(8)(-x)=7x+2\\\\32-8x=7x+2\qquad\text{subtract 32 from both sides}\\\\32-32-8x=7x+2-32\\\\-8x=7x-30\qquad\texy{subtract}\ 7x\ \text{from both sides}\\\\-8x-7x=7x-7x-30\\\\-15x=-30\qquad\text{divide both sides by (-15)}\\\\\dfrac{-15x}{-15}=\dfrac{-30}{-15}\\\\x=2[/tex]
