Solve to find the value for x in the linear equation: 3(−4x + 5) = 12.

1. Use the distributive property:



2. Use the subtraction property of equality:

3. Division property of equality:


3(−4x) + 3(5) = 12

−12x + 15 = 12

−12x + 15 − 15 = 12 − 15

−12x = −3

Answer:

Solving the linear equation
3(-4x + 5) = 12 we get
\mathbf{x=(1)/(4)}

Explanation:

We need to solve to find the value for x in the linear equation:
3(-4x + 5) = 12

1. Use the distributive property:

Multiply 3 with terms inside the bracket


3(-4x + 5) = 12\\3(-4x)+3(5)=12\\-12x+15=12

2. Use the subtraction property of equality:

Subtracting 15 on both sides


-12x+15-15=12-15\\-12x=-3

3. Division property of equality:

Divide both sides by -12


(-12x)/(-12)=(-3)/(-12)


x=(1)/(4)

So, solving the linear equation
3(-4x + 5) = 12 we get
\mathbf{x=(1)/(4)}
