Answer:
an infinite number of solutions
Step-by-step explanation:
−3x −17 = −17 −3x
left side = right side TRUE because -3x-17 is the same as -17-3x
we can rearrange the the equation
−3x −17 +17 = −17 +17−3x, add 17 on both sides of the equations
-3x = -3x, divide both sides by (-3)
x = x
Since this equation is <u>always true ( for any number ) </u>we have <u>an infinite number of solutions</u> (since there are is an infinity of numbers.)
Answer:

Step-by-step explanation:
The action that creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated is " Multiply the second equation by -4 to get -16x - 4y = -80 " ⇒ answer a
Step-by-step explanation:
To solve a system of equation using the elimination method
- Make the coefficient of one variable in the two equations have same values and different sign
- Add the two equation to eliminate this variable
- Solve the resulting equation to find the other variable
- Substitute the value of the other variable in one of the two equations to find the value of the eliminating variable
The system of equation is :
2x + 4y = 14 ⇒ 1st equation
4x + y = 20 ⇒ 2nd equation
You can multiply first equation by -2 to get
-4x - 8y = -28 ⇒ 3rd equation
When you add the second and the third equations x will eliminated
<em>OR</em>
You can multiply second equation by -4 to get
-16x - 4y = -80 ⇒ 3rd equation
When you add the first and the third equations y will eliminated
The action that creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated is " Multiply the second equation by -4 to get -16x - 4y = -80 "
