Please help me on this ​
Sveta_85 [38]

Answer:

14.125

Step-by-step explanation:

You combine the two equations and get

8x - 23

and since they're in a 90 degree angle you do

8x - 23 = 90

 add 23 to both sides

8x =113

divide 113 by 8 and you get 14.125 and if you plug it in for both x's you get 24.625 + 65.375 you get an even 90

Solve the system of equations by the substitution method
slava [35]

Answer:

x=0.5

y = 10.5

Step-by-step explanation:

y = 3x + 7

y = 5x + 8

3x + 7 = 5x + 8

3x - 5x=  8 - 7

2x = 1

x= 1/2

x=0.5

y = 5x + 8

y = 5(0.5) + 8

y = 2.5 + 8

y = 10.5
