Solución
Solve the equation \( 13=-7x-18 \).
Solve the equation by following steps:
- step0: Solve for \(x\):
\(13=-7x-18\)
- step1: Swap the sides:
\(-7x-18=13\)
- step2: Move the constant to the right side:
\(-7x=13+18\)
- step3: Add the numbers:
\(-7x=31\)
- step4: Change the signs:
\(7x=-31\)
- step5: Divide both sides:
\(\frac{7x}{7}=\frac{-31}{7}\)
- step6: Divide the numbers:
\(x=-\frac{31}{7}\)
The solution to the equation \(13=-7x-18\) is \(x=-\frac{31}{7}\) or \(x=-4.428571\).

To solve the equation \( 13 = -7x - 18 \), first, we can add 18 to both sides: \[ 13 + 18 = -7x \] This simplifies to: \[ 31 = -7x \] Now, divide both sides by -7 to isolate \( x \): \[ x = \frac{31}{-7} = -\frac{31}{7} \] This can also be expressed as a decimal: \[ x \approx -4.43 \] So the solution is \( x = -\frac{31}{7} \) or approximately \( -4.43 \).
