FAQs on Data Sufficiency Practice Question - 1 Video Lecture - Crash Course for GMAT

1. How do I solve algebraic equations with variables on both sides?

Ans. To solve algebraic equations with variables on both sides, start by combining like terms on each side of the equation. Then, move all the variable terms to one side and all the constant terms to the other side. Finally, simplify and solve for the variable.

2. Can you explain how to solve quadratic equations using factoring?

Ans. To solve a quadratic equation using factoring, first, set the equation equal to zero. Then, factor the quadratic equation into two binomials. Next, set each binomial equal to zero and solve for the variable. The solutions obtained will be the roots of the quadratic equation.

3. What is the method to solve systems of linear equations using substitution?

Ans. To solve a system of linear equations using substitution, start by solving one equation for one variable. Then, substitute the expression for that variable in the other equation. Simplify and solve for the remaining variable. Finally, substitute the value of the second variable back into either of the original equations to find the value of the other variable.

4. How can I simplify algebraic expressions by combining like terms?

Ans. To simplify algebraic expressions by combining like terms, identify the terms with the same variables and exponents. Then, add or subtract the coefficients of those terms. If there are multiple terms with the same variables, combine them into a single term. Repeat this process until no more like terms can be combined.

5. What is the process to solve absolute value equations?

Ans. To solve absolute value equations, start by isolating the absolute value expression on one side of the equation. Then, remove the absolute value bars and consider both the positive and negative cases. Solve each case separately and check if the obtained values satisfy the original equation.
