QUESTION:

What is the solution to -3/4x + 2 is less then or equal to -7

ANSWER:


\green{{x ≥ 12}}

STEP-BY-STEP EXPLANATION:

First, Simplify each term

Combine
{x} and
{(3)/(4)}


\green{{-(x × 3)/(4) + 2 ≤ - 7}}

Move 3 to the left of
{x}


\green{{-(3x)/(4) + 2 ≤ - 7}}

Second, Move all terms not containing
{x} to the right side of the inequality

Subtract 2 from the both sides of the inequality


\green{{-(3x)/(4) ≤ - 7 - 2}}

Subtract 2 from - 7


\green{{-(3x)/(4) ≤ - 9}}

Third, Multiply each term in
{-(3x)/(4) ≤ - 9 by - 1}

When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign


\green{{-(3x)/(4) × - 1 ≥ ( - 9) × - 1}}

Fourth, Multiply
{-(3x)/(4) × - 1}

Multiply - 1 by - 1


\green{{1(3x)/(4) ≥ ( - 9) × - 1}}

Multiply
{(3x)/(4)} by 1


\green{{(3x)/(4) ≥ ( - 9) × 1}}

Multiply - 9 by - 1


\green{{(3x)/(4) ≥ 9}}

Multiply both sides of the equation by 4


\green{{3x ≥ 9 × (4)}}

Multiply 9 by 4


\green{{3x ≥ 36}}

Fifth, Divide each term by 3 and simplify

Divide each term in
{3x ≥ 36 by 3}


\green{{(3x)/(3) ≥ (36)/(3)}}

Sixth, Cancel the common factor of 3

Cancel the common factor


\red{{(3x)/(3)}}
\green{{(36)/(3)}}

Divide
{x} by 1


\green{{x ≥ (36)/(3)}}

Lastly, Divide 36 by 3


\green{\boxed{x ≥ 12}}

hope it's helps
