X + 3y =- 12 y+ 3 =- {(x – 3)

Mathematics
1 answer:
fenix001 [56]3 years ago
8 0

Answer:

x = 6, y = -6

Step-by-step explanation:

solve for x and y

x + 3y =  -12

y + 3 = -x + 3

add

(x + 3y)  +  -x + 3  =  -12 + y + 3

3y + 3 = y - 9

2y + 3 = -9

2y = -12

y = - 6

x + 3(-6) = -12

x - 18 = -12

x = 6

Evaluate each expression using the values m = 7, r = 8, and t = 2.
user100 [1]

So I'll walk through the first 2. Then please try the other ones and let me know if you run into more problems.

5m-6

If m is equal to 7, then replace m with 7.

5(7)-6

5x7=35 so the expression is now 35-6. Solve.

35-6=29

So that was the first one.

4m+t

We just do what we do with the first problem.

4(7)+(2)

4x7=28 so the expression is 28+2.

28+2=28

---

hope it helps

p.s. When there is subtraction, add. When there is division, multiply to cancel that out. When there is multiplication, divide to cancel. etc.
