Question

plz solve this sum tomorrow is my test 6,8​

Answer 1

Answer:

Step-by-step explanation:

6. 8x + 4 = 3(x-1)+7

8x+4=3x-3+7

8x-3x=-3+7-4

5x=0

X=0/5=0

8.2x/3+1=7x/15+3

2x/3-7x/15 = 3-1

Take the lcm of 3 and 15 = 15

10x-7x/15=2

3x= 2*15

x= 30/3

x=10

Please mark as branliest

Answer 2

Step-by-step explanation:

(6) 8x + 4 = 3(x-1) + 7

8x + 4 = 3x - 3 + 7

8x + 4 = 3x + 4

8x - 3x = 4 - 4

5x = 0

x = 0

verification, put x = 0 in eq.

8(0) + 4 = 3(0 - 1) + 7

0 + 4 = 3(-1) + 7

4 = -3 + 7

4 = 4

(8) 2x/3 + 1 = 7x/15 + 3

2x/3 - 7x/15 = 3 - 1

(10x - 7x)/15 = 2

3x/15 = 2

3x = 2 × 15

3x = 30

x = 10

verification

2(10)/3 + 1 = 7(10)/15 + 3

20/3 + 1 = 70/15 + 3

(20 + 3)/3 = (70 + 45)/15

23/3 = 115/15

23/3 = 23/3
