Use the substitution method to solve the system of equations choose the correct ordered pairs x plus 2y 12 y x plus 3?
Without any equality signs they can't be considered to be equations. But if you mean: x+2y =12 and y = x+3 then the solution is as follows x+2y = 12 -x+y = 3 Adding the equations together: 3y = 15 and y = 5 By substitution: x = 2 Solution: x = 2 and y = 5
How do you solve mathematical equations using the subsitution method?
Say you have a pair of equations like a+b=1 and 2a+3b=5. To solve using substitution you would set one equation against one variable (say a=1-b) then plug that into the other (2(1-b)+3b=5), then solve for the one variable you have there and then plug that result into the other equation (in this case b=3 and a=-2).
Two numbers have a product of 20 and a sum of 9?
To solve this question use a two variable system of equations. First assign a variable to each number: a=first number b=second number Then use the information in the problem to write two equations They have a product of 20 translates to: a x b =20 They have a sum of 9 translates to: a + b =9 Use the method of substitution. Isolate one variable in the 1st equation: a= 20/b Plug it into the 2nd equation: (20/b) + b = 9 Solve for b: b = 5 Now put b back into the 2nd equation: a + 5=9 Solve for a: a = 4 So the solution is 4 and 5.

Solve the system of equation using substitution 2x plus 5y equals 2 and -3x-y equals -3?
2x + 5y = 2-3x - y = -3from the second equation:-y = -3 + 3xy = 3 - 3xsubstitute this value in the first equation:2x + 5(3-3x) = 22x + 15 - 15x = 2-13x + 15 = 2-13x = 2 - 15-13x = -13so, x = 1Now, solve for y :y = 3 - 3xy = 3 - 3 (1)y = zero

How do you solve systems of equation algebraically?
There are 5 ways to solve a system. The most popular is to write both in standard notation then add the equations together. The easiest to explain is to use substitution. Solve one for one of the variables then substitute in the other equation. The other ways to solve are to use graphing and find the intersection. Determinants and matrices are the other two ways.
Solve the system using substitution 5x-y equals 5 diveded by5x-3y equals 15?
5x - y = 55x - 3y = 15from the first equation:5x = 5 + y , substitute it in the second equation:5 + y - 3y = 155 -2y = 15-2y = 15 - 5-2y = 10y = -5Now,solve for x :5x = 5 +y5x = 5 -5 = zerox = zero
How do you solve each system by substitution or addition 2y-x equals 3 and x equals 3y-5?
Add the two equations together. The x disappears. 2y - x = 3 + x = 3y - 5 ------------------------ 2y = 3y -2 Can you finish it from there?
Solve this system of equations using substitution. Put your answer in ordered pair form (x y). x plus 7y 39 3x - 2y 2?
To solve the system of equations given by ( x + 7y = 39 ) and ( 3x - 2y = 2 ) using substitution, we can first solve the first equation for ( x ): ( x = 39 - 7y ). Substituting this into the second equation gives ( 3(39 - 7y) - 2y = 2 ). Simplifying this results in ( 117 - 21y - 2y = 2 ), or ( 117 - 23y = 2 ), leading to ( 23y = 115 ) and ( y = 5 ). Plugging ( y = 5 ) back into ( x = 39 - 7(5) ) gives ( x = 4 ). Thus, the solution in ordered pair form is ( (4, 5) ).

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 the Substitution method to solve the system of equations y - 2x equals -5 3y - x equals 5?
From first equation: y = 2x - 5Substitute this in second equation: 3(2x - 5) - x = 5, ie 6x - 15 - x = 5ie 5x = 5 + 15 so x = 4 and y = 3
