Question

1.3 general linear equations: prob (1 point) -7x + (-12)x + 11 = 18 + 13 has solution: x = you have attempted this problem 0 times. you have unlimited attempts remaining.

Explanation:

Step1: Combine like - terms on both sides

Combine the $x$ - terms on the left - hand side: $-7x+( - 12)x=-7x - 12x=-19x$, and on the right - hand side: $18 + 13 = 31$. So the equation becomes $-19x+11 = 31$.

Step2: Isolate the term with $x$

Subtract 11 from both sides of the equation: $-19x+11-11=31 - 11$, which simplifies to $-19x=20$.

Step3: Solve for $x$

Divide both sides of the equation by - 19: $x=\frac{20}{-19}=-\frac{20}{19}$.

Answer:

$-\frac{20}{19}$
