What is 4x+1=25
A 8
B 24
C 6
D 26

C

Step-by-step explanation: 4x+1=25

Subtract the 1 from 25, you get 4x=24

Then divide 24/4 = 6

entering that problem on the tube might get you an answer

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
