How many solutions does this system of equations have 2x-3y equals -14 4x-6y equals -28?
The equations are identical in value, ie the second is merely twice the first...
How doI solve system of equations by substitution?
Assuming the simplest case of two equations in two variable: solve one of the equations for one of the variables. Substitute the value found for the variable in all places in which the variable appears in the second equation. Solve the resulting equation. This will give you the value of one of the variables. Finally, replace this value in one of the original equations, and solve, to find the other variable.
What is the value of the y variable in the solution to the following system of equations- 3x - 6y equals 3 7x - 5y equals -11?
If "equations-" is intended to be "equations", the answer is y = -2. If the first equation is meant to start with -3x, the answer is y = 0.2

What is the substitution method for y equals 5x plus 8 and y equals 10x plus 3?
5x+8 = 10x+35x-10x = 3-8-5x = -5x = 1 and by substituting the value of x into the equations y = 13
7x - 5y equals 76 4x plus y equals 55?
To solve this system of equations, we can use the method of substitution or elimination. Let's use the substitution method. From the second equation, we can express y as y = 55 - 4x. Substitute this expression for y in the first equation: 7x - 5(55 - 4x) = 76. Simplify this equation to solve for x. Then, substitute the value of x back into one of the original equations to find the value of y.
Use addition or substitution to find the value of x for this set of equations 2x - 3y equals -15 x equals 4y?
2x - 3y = -15x => -3y = -17x => -21y = -119x 2x - 3y = 4y => 2x = 7y => 21y = 6x so now you can add the two equations. 0 = -113x x=0 now plug back in 2*0 - 3y = -15*0 -3y = 0 y=0.
Use addition or substitution to find the value of x for this set of equations 12x-5 equals 30 and y equals 2x-6?
12x - 5 = 30Add 5 to each side:12x = 35Divide each side by 12:x = 35/12=======================y = 2x - 6Substitute the value of 'x' :y = 2(35/12) - 6Clear parentheses:y = 35/6 - 6y = 35/6 - 36/6y = -1/6
Y equals 4x minus 8 and y equals 2x plus 10 sole using system of equations using substitution?
y = 4x-8 and y = 2x+10 4x-8 = 2x+10 4x-2x = 10+8 2x = 18 x = 9 Substitute the value of x into the original equations to find the value of y: Therefore: x = 9 and y = 28

Use the substitution method to solve the system of equations Enter your answer as an ordered pair 3x plus y equals 10 y equals x - 2?
3x+y = 10 y = x-2 Substitute the value of y into the top equation: 3x+x-2 = 10 => 4x = 10+2 => 4x = 12 => x = 3 Substitute the value of x into the original equations to find the value of y: So: x = 3 and y = 1
What is the value of in the 40mm equations 100mm equals 11.70 and 150mm equals 34.20?
What is the value of what. You didnt specify. And this equations dont make sense. 100millimeters can equal 11.70 nothing and 150millimeters can equal 34.20 when 100mm equals 11.70. And what is the random 40mm for
