Solve the linear equation 4x + 3 = 7 by subtracting 3 from both sides to get 4x = 4, then dividing by 4 to find x = 1.
what is the solution to this equation: 4x + 3 =7
Prove algebraically that the expression n^2 - 2 - (n - 2)^2 is always an even number by expanding the brackets and factoring out a 2.
Simplify the rational expression (x^2 + x)/x by factoring out x to get x + 1, then solve x + 1 = 8 to find x = 7, so 2√x = 2√7 ≈ 5.29.
Solve the two-step equation 11 = 4x + 7 by subtracting 7 from both sides, then dividing by 4. The solution is x = 1.
Step-by-step solutions for simplifying complex radical expressions and evaluating algebraic polynomials with square roots based on math textbook problems.
Simplify x/(x − 7) + (4x − 1)/(x − 7) by adding the numerators and keeping the common denominator. The result is (5x − 1)/(x − 7), where x ≠ 7.
