How do you solve 3x plus 2y equals 7?
You cannot solve one linear equation in two unknown variables.
What property of equality would you use to solve x over 6 equals 7?
That you can multiply both sides of the equation by any number.Thus, multiplying by 6 gives (x/6)*6 = 7*6 x = 42.
How do you solve the equation 5n - 7 equals 38?
To solve the equation 5n - 7 = 38, do whatever you do to one side of the equals sign to the other. So, add 7 to both sides. 5n = 38. Now divide both sides by 9. 5 = 9. To check your answer, replace the n with 9 and solve the equation. 5 x 9 - 7 = 38. Do the multiplacation first. 45 - 7 = 38. 38 = 38. The answer is correct.
Solve by substitution y equals -4x - 7 and y equals 3x?
The easiest way to solve this system of equations is to solve for a variable in one of the equations. In the second equation, y = 3x. This can be substituted into the first equation: y = -4x - 7; 3x = = -4x - 7; 7x = -7; x = -1. Since we have determined that x equals -1, we can then substitute -1 into either equation to find our corresponding y-value. Thus: y = 3x; y = 3(-1) y = -3. Thus, the solution to this system of equations is (-1, -3).
