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) ).

What is the ordered pair for 3x 5y equals 21 and -9x 4y equals -6?
To find the ordered pair for the equations (3x + 5y = 21) and (-9x + 4y = -6), we can solve this system of equations. By using substitution or elimination methods, we find that (x = 3) and (y = 2). Thus, the ordered pair is ((3, 2)).
How do use substitution when solving system of equations?
You use substitution when you can solve for one variable in terms of the others. By substituting, you remove one variable from the equation, which can then be solved. Once you solve for one variable, you can use substitution to find the other.
How do you solve system of equations by using the substitution method?
To solve a system of equations using the substitution method, first, solve one of the equations for one variable in terms of the other. Then, substitute this expression into the other equation to eliminate that variable. This will result in a single equation with one variable, which can be solved for its value. Finally, substitute this value back into the original equation to find the value of the other variable.
How do you solve system of eqaution by subsitution?
To solve a system of equations by substitution, first solve one of the equations for one variable in terms of the other. Then, substitute this expression into the other equation. This will give you an equation with only one variable, which you can solve. Finally, substitute back to find the value of the other variable.

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.
