Type the algebraic equation for this statement. let a represent the unknown number. six times a number minus five is less than twice the number plus ten.

6a - 5 < 2a + 10

4a - 5 < 10

    4a < 15

     a <

i believe the correct answer is b.

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
