Answer:
y = -1 x = 4
Step-by-step explanation:
(X+3y=1) 5 Multiply this equation by 5 to cancel out the x
-5x+4y=-24
-5x + 4y= -24
+ 5x + 15y = 5 Add both equations together
19y = -19 Divide both sides by 19
y = -1
Plug -1 for y into one of the equations
x + 3(-1) = 1 Multiply 3(-1)
x - 3 = 1
+ 3 + 3 Add 3 to both sides
x = 4

Step-by-step explanation:
Answer: c
Step-by-step explanation:
5 times a number plus two is 17
5(x) + 2 = 17
isolate the x, do the opposite of PEMDAS
(Note: What you do to one side you do to the other, because of equal sign)
5x + 2 (-2) = 17 (-2)
5x = 15
5x/5 = 15/5
x = 3
