Answer:

x = - 3

Step-by-step explanation:

Given the 2 equations

y = \frac{1}{3} x + 7 → (1)

y = 3x + 15 → (2)

Since both equations express y in terms of x, equate the right sides

3x + 15 = \frac{1}{3} x + 7

Subtract \frac{1}{3} x from both sides

\frac{8}{3} x + 15 = 7 ( subtract 15 from both sides )

\frac{8}{3} x = - 8 ( multiply both sides by 3 )

8x = - 24 ( divide both sides by 8 )

x = - 3

6. unlimited answers

7. There's no answer to this question .

Step-by-step explanation:

___________________

4. solution :

-20(2-4) = 2((5×-4) -4) =

-40 = -48 × impossible

___________________

5. solution :

-3+4x+12x+24 = 28x +12-3

-3+24-12+3=28x-12x-4x

27-15=12 = 2x - 16x =12x

12 = 12x

x =1

__________________

6. solution :

24-3x+9-6 = -8x+20+5x+7

8x-5x-3x = -24-9+6+20+7

0=0

x can be every number you think because they are always equal to each other .

examination :

if you consider x as 1 :

24-3+9-6=-8+20+5+7

24=24

or if you consider x as 2 :

24-6+9-6 = -16+20+10+7

21 = 21

__________________

7 . solution :

3(x-2) = 3x+4

3x-6 = 3x+4

3x-3x = 10

0 = 10

if you consider x as 1 :

3-6 = 3+4

-3 = 7 × impossible .

emmasim [6.3K]
7(-3) is an example of multiplication. What the question wants you to do is multiply the outside number (7) by the inside number (-3).
Basically you are just multiplying -3 x 7.
Your product is -21
