4b plus 3 equals 15 solving two step equations?
4b+3=15 4b=15-3 b=(15-3)/4 b=3
How do you find the solutions of the simultaneous equations of 2x plus 5y equals 16 and -5x-2y equals 2 showing work in step by step stages?
1 If: 2x+5y = 16 and -5x-2y = 2 2 Then: 2*(2x+5y =16) and 5*(-5x-2y = 2) is equvalent to the above equations 3 Thus: 4x+10y = 32 and -25x-10y = 10 4 Adding both equations: -21x = 42 or x = -2 5 Solutions by substitution: x = -2 and y = 4
Slove multi-step equations 4n-2n 4?
If you mean: 4n-2n = 4 then 2n = 4 and n = 2
When solving a system of equations what does 4 equals 4 mean?
three things: 1) that the value of 4 is equal to the value of 4. 2) you did not obtain any revealing information. 3) your strategy for solving that system of equations was not good.
What is the solution to the following system of equations 2x minus 3y equals 4 and 4x plus y equals -6?
{-1,-2}
How do you do two step equations?
You will have to break it down, for example: 5x + 40= 60 -40 -40 ----------- 0 20 so 20 divided by 5 is 4 so x equals 4, thats how you do it,.
Answer this equations x plus 42y equals 4?
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
The equations of two lines are 6x-y equals 4 and y equals 4x plus 2. What is the value of x in the solution for this system of equations?
x=3
What is the correct classification of this system of equations -2x plus y equals 7 3y equals 6x plus 4?
Inconsistent linear equations in two variables.
4b plus 3 equals 15 solving two step equations?
4b+3=15 4b=15-3 b=(15-3)/4 b=3
What is a two step equation that equals -2?
An example of a two step equation that equals 2 is 4 + 2x = 2. In this equation, x = -1.
What is 4a equals 4-b 4a equals 2-b?
They appear to be the equations of two parallel lines in the a-b plane.
What is the common point of these equations x plus 2y equals 6 x plus y equals 2?
When x = -2 then y = 4 which is the common point of intersection of the two equations.
How many solutions does 2x plus y equals 5 and 2x plus y equals 4 have?
None. When these two equations are graphed, the two lines are parallel. Since they never intersect, there is no point that satisfies both equations.
What are the solutions to -x squared plus 2x plus 4 and x-2?
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
What kind of line is this equation 2y plus 4 equals 10 y equals -2x plus 5?
There are two equations in the question, not one. They are the equations of intersected lines, and their point of intersection is their common solution.
What is y equals -02 equals x squared plus x plus 4?
Two equations: a linear one in y and a quadratic in x.
