12x + 4x + 25y + 15y A. 2(8x + 10 B. 4(4x + 10) C. 5(3x + 5y D. 8(2x + 5y

109 x. A. Try your expression with a real number to see if it makes sense. For ... negative is a positive. C:X-3 ya tx combine like terms. 2x-3y². (De) 4x3y - 6xy3 ... B. (94-6) = (12-4x). Solve for x distribute on each side. if you use a calculator, put the ... distribute solve: 3(x+2). 3x +6. +57. 8 X+. 1 -6. = 5(-2-x). < -10 -5x. +5*. < -10.

Step-by-step explanation:

The answer to 12x + 4x + 25y + 15y is 16x+40y for sure, I did it multiple times.

I don't see that answer in what you provided.

Step-by-step explanation:

Is there anything more that I can do to help you?

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
