x-0=3 aby 2003 7.0 you pr120) Ytrepto- interapt.co. Solve each system by substitution. 43 o-y-3 ANTOTA 5) y = 4r-9 -3 y=r- 3 6) 4x + 2 y = 10 x - y = 13

Respuesta :

4x+2y=10

x-y=13

Solve the second equation for x:

x = 13+y

Replace x=13+y in the first equation, and solve for y:

4 (13+y) + 2y = 10

52+4y+2y=10

Combine like terms

4y+2y = 10 - 52

6y= -42

y= -42/6

y= -7

Replace y=-7 on any equation and solve for x:

x-y=13

x-(-7) =13

x+7 =13

x=13-7

x= 6

Solution: (6,-7)
