How would you solve 5(x-1)+3=13

x = 3

Step-by-step explanation:

5(x-1)+3=13

Distribute the 5

(5x - 5) + 3 = 13

5x - 5 + 3 = 13

x = 3

you cant answer this dummy

step-by-step explanation:

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
