Y equals x plus 3 and 3x-y equals 5?
Solve this simultaneous equation using the elimination method after rearraging these equations in the form of: 3x-y = 5 -x+y = 3 Add both equations together: 2x = 8 => x = 4 Substitute the value of x into the original equations to find the value of y: So: x = 4 and y = 7
5 What advantage is there to using algebraic equations instead of numerical values when defining the dimensions of a CAD model?
Dimensions can be more accurately calculated when using algabreic equations rather than numerical values.
What are the pros and cons of using the substitution or elimination method in equations?
A pro for solving equations through graphing can allow one to visualize problems which can allow one to make better sense to the problem. However, fractions, and decimals can be very difficult to plot accurately. Furthermore, solutions could fall outside of the boundaries of a graph making them impossible to see with a graph. A pro for solving equations through either the methods of substitution and elimination allow one to achieve an exact answer regardless of fraction, decimal, or integer. However, by using these methods one will have a more difficult time with visualization without the use of a graph.
Solve by using the elimination method for 9x-9y equals 36 and 7y-3x equals -14?
9x-9y = 36 => x-y = 4 3(-y+x = 4) 7y-3x = -14 Multiply all terms in the top equation by 3: -3y+3x = 12 7y-3x = -14 Add both equations together: 4y = -2 Divide both sides by 4: y = -0.5 Substitute the value of y into the original equations to find the value of x: x = 3.5 and y = -0.5
Solve the following system of equations using substitutions 2x plus 3y equals -1 and 5x-2y equals -12?
First get y in terms of x: 5x-2y=-12 ----- -2y=-12-5x ------ y=6+(5/2)x Sub into other equation: 2x+3y=-1 ---- 2x+3(6+(5/2)x)=-1 Solving for x gets: x= -2 Sub into other equation: 5x-2y= -12 --- 5(-2)-2y= -12 --- y=1 So x= -2, and y= 1
How do you Solve this system of equations using the addition method 6a - 5b equals 9 2a plus 5b equals 23?
the answer
Solve this system of equations using the addition method x plus y equals 6?
When talking about a "system of equations", you would normally expect to have two or more equations. It is quite common to have as many equations as you have variables, so in this case you should have two equations.
Translate this word problem as a system of equations and then solve using substitution?
A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.
Solve the system of equations using linear combination a plus c equals 9 8a plus 4.5c equals 58?
a=5: c=4
Solve the system using elimination 3x -9y equals 3?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
Can you solve the system using elimination 3x plus 9y equals 3?
No. Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
What is a solution to the following system of equations using substitution -5x plus y equals -5?
-10
Solve the system of equations using the elimination method negative x plus y equals negative 3 and 3x plus 2y equals 9?
By elimination: x = 3 and y = 0
What are two or more linear equations using the same variables called?
A system of linear equations.
Is using four equations to solve a problem called a four-order system?
No. The word "order" has various meanings in math, but I don't think this is one of them.
How do you solve 3 dimensional equations?
You can solve the system of equations with three variables using the substitute method, or using matrix operations.
Solve the following system of equations using sustitution x6y-4 x-2y 28?
To solve a system of equations, you need equations (number phrases with equal signs).
