Answer:
Step-by-step explanation:
I don't know if this is what you are looking for but, I would use substitution to solve what x and y are
6x+2y = 1
is the same as -6x-2y= -1 because if you multiply everything by -1 it will equal
6x+2y = 1
so now you have
6x+2y = 1
6x+2y = 1
I would set the equation equal to one variable and substitute.
6x+2y = 1 = 2y = 1 - 6x = y = (1/2) - (6x/2) = y = (1/2) - 3x
now plug in (1/2) - 3x in to one of the y's because they are the same equation
6x + (1/2) - 3x = 1
subtract 1/2
6x - 3x = 1/2
subtract the x's
3x = 1/2
now divide both sides by 3
x = (1/2)/ 3
x = 1/6
now that you know what x equals, plug that into the equation and find y
6(1/6) + 2y = 1
1 + 2y = 1
subtract 1
2y = 0
now divide to find y
y = 0/2
y = 0
so
x = 1/6 and y = 0

Answer:
The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
We can substitute a definition of one of the variables by rearranging the first equation.
We set the first equation equal to one of our two variables.
Now we substitute this equality into our second equation
20x+29 Parenthesis are supposed to be solved first, but due to the variable (x) i multiplied 5 (distributive property) leaving the 9 alone ... you just add it to the equation .....which you can't find x because you don't know what the whole equation equals to.
