Answer
\( x=-5 \)
Solution
Solve the equation \( \frac{3x+7}{2}=-4 \).
Solve the equation by following steps:
- step0: Solve for \(x\):
\(\frac{3x+7}{2}=-4\)
- step1: Cross multiply:
\(3x+7=2\left(-4\right)\)
- step2: Simplify the equation:
\(3x+7=-8\)
- step3: Move the constant to the right side:
\(3x=-8-7\)
- step4: Subtract the numbers:
\(3x=-15\)
- step5: Divide both sides:
\(\frac{3x}{3}=\frac{-15}{3}\)
- step6: Divide the numbers:
\(x=-5\)
The solution to the equation \( \frac{3x+7}{2}=-4 \) is \( x=-5 \).

To solve for \( x \), start with the equation: \[ \frac{3x + 7}{2} = -4 \] First, multiply both sides by 2 to eliminate the fraction: \[ 3x + 7 = -8 \] Next, subtract 7 from both sides: \[ 3x = -8 - 7 \] \[ 3x = -15 \] Now, divide both sides by 3: \[ x = -5 \] Thus, the simplified answer is: \[ x = -5 \]
