Answer:
Infinitely many solutions
Step-by-step explanation:
If we have a system of equation like:
2x+y=4
6x+3y=12
If we make y the subject in the first equation and substitute into the second equation, we get:
6x+3(4-2x)=12
We expand to get:
6x+12-6x=12
6x-6x+12=12
Now the variable adds out to give:
12=12
This statement is true so the equation has infinitely many solution.
STEPS:
-1-6X-6>-11-7X
GROUP LIKE TERMS
-6X-1-6>-11-7X
SUBTRACT THE NUMBERS:-1-6=-7
-6X-7>-11-7X
ADD SEVEN TO BOTH SIDES
-6X-7+7>-11+7-7X
SIMPLIFY
-6X>-7X-4
ADD 7X TO BOTH SIDES
-6X+7X>-7X+7X-4
SIMPLIFY
X>-4
SO THE ANSWER IS X>-4
Answer:
25+n=61
Step-by-step explanation:
megan has 25 numbers so we no to put 25 in the equation but we dont know abbys so we use n to represent that we also know both of thier numbers total equals 61 so we add megans and the variable to signify abbys numbers and set it equal to the amount they both have in total because we know that both of thiers together equals 61.hope this helps!!!
