Question

fatima quezada math 9 test 1 corrected 1) 8(3x - 5)-4(x + 3)=12

Explanation:

Step1: Expand the expressions

$8(3x - 5)-4(x + 3)=12$ becomes $24x-40 - 4x-12 = 12$.

Step2: Combine like - terms

$(24x-4x)+(-40 - 12)=12$, so $20x-52 = 12$.

Step3: Isolate the variable term

Add 52 to both sides: $20x-52 + 52=12 + 52$, which gives $20x=64$.

Step4: Solve for x

Divide both sides by 20: $x=\frac{64}{20}=\frac{16}{5}=3.2$.

Answer:

$x = 3.2$
