5x+2y=29
x+4y =13
i don’t know that answer

x=71/9, y= -47/9

Step-by-step explanation:

5x+2y=29

x+4y=13 subtract 4y from both sides

x= -4y+13 substitute on the first one

5( -4y+13) + 2y = 29 distribute in parenthesis

-20y - 65 +2y =29 add 65 to both sides

-20y +2y = 29+65 combine like terms

-18y = 94 divide by -18 both sides

y= 94/-18= -47/9

substitute y =-47/9 in x=-4y+13

x=-4(-47/9)+13=(188/9)+13=188+117/9=71/9

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
