Answer:
x < -7
Step-by-step explanation:
An inequality is solved similar to an equation with the exception that when multiplying or dividing by a negative coefficient, the sign must flip in the other direction. The original inequality is:
-6x > 42
To solve, you need to divide both sides of the inequality by -6, however, since you are dividing by a negative coefficient, the sign need to flip the other way:
-6x/-6 > 42/-6 = x < -7
Answer: to solve the 3 unknown variables X, Y and Z in a set of 3 equations. Each equation has containing the unknown variables X, Y and Z. This 3 equations 3 unknown variables solver computes the output value of the variables X and Y with respect to the input values of X, Y and Z coefficients. In mathematic calculations, there are many situation arises where the usage of equation containing 3 unknown variables need to be solved prior to go further with the calculations. Therefore when it comes to online calculation, this Find the value of X, Y and Z calculator is an essential tool to assist you to find out the variable values given in the equation.
Step-by-step explanation: X = 2
Y = -1
Z = 1
One value: would be a single valued function, or just one answer.
Real numbers would be: natural numbers, whole numbers, integers, rational numbers (fractions and repeating or terminating decimals), and irrational numbers.
No solution: there is no answer to the question.
