question
solve for x.
4(x + 4) + 3x - 5 = 4
answer attempt 1 out of 2
x = submit answer

Explanation:

Step1: Expand the expression

$$4(x + 4)+3x - 5=4$$
$$4x+16 + 3x-5 = 4$$

Step2: Combine like - terms

$$(4x+3x)+(16 - 5)=4$$
$$7x+11 = 4$$

Step3: Isolate the variable term

Subtract 11 from both sides:
$$7x+11-11=4 - 11$$
$$7x=-7$$

Step4: Solve for \(x\)

Divide both sides by 7:
$$x=\frac{-7}{7}$$

Answer:

\(x=-1\)
