plz solve this sum tomorrow is my test 6,8

Answers
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

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
