What is 'basic math' and why is it so important?
Basic Math is the simple operations such as addition, subtraction, multiplication & division. It is important because every mathematical concept is built on top of these 4 operations.
Solve the equation 5(- 3x - 2) - (x - 3) = -4(4x + 5) + 13
Given the equation 5 (- 3 x - 2) - (x - 3) = - 4 (4 x + 5) + 13 Multiply factors -15 x - 10 - x + 3 = - 16 x - 20 + 13 Group like terms. - 16 x - 7 = - 16 x - 7 Add 16x + 7 to both sides and write the equation as follows 0 = 0 The above statement is true for all values of x and therefore all real numbers are solutions to the given equation.
