Solve the system of linear equations by elimination. check your solution. x-3y=1 4x + 5 y =4

X-3y= 1
4x+5y=4
set an x equation or vise versa
x=3y+1 ( now plug in the x equation to the other equation)
4 ( 3y+1) +5y = 4
12y + 4 + 5y =4
17y= 0
y=0
Now solve for x by plugging in the y value
4x + 5 (0) =4
4x=4
x=1

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
