Question

deltamath linear equations w/ distribution (lev 3) score: 0/4 penalty: none question solve for x: 3x - 2(8x + 8)=-(7x - 10)-2x answer attempt 1 out of 2 x =

Explanation:

Step1: Apply distributive property

$3x-16x - 16=-7x + 10-2x$

Step2: Combine like - terms on both sides

$(3x-16x)-16=(-7x-2x)+10$, so $-13x-16=-9x + 10$

Step3: Add $13x$ to both sides

$-13x + 13x-16=-9x+13x + 10$, which simplifies to $-16 = 4x+10$

Step4: Subtract 10 from both sides

$-16-10=4x+10 - 10$, getting $-26 = 4x$

Step5: Solve for $x$

$x=\frac{-26}{4}=-\frac{13}{2}$

Answer:

$x =-\frac{13}{2}$
