Question

hello I am having trouble in answering this properly
1) 4+8a=60
the answer should be a=7 but I am getting a=6.75
2) 50-3s=8
the answer should be s=14 but I am getting s=19 1/3
3) 5x/2 -7=11/2
the answer should be x=5 but I am getting x=5/s

I am really having trouble with these
the fastest and the best will be marked as the brainliest

Answer 1

I) 8a=60-4

8a=56

a = 56/8

a= 7

2) -3x = 8-50

-3x = -42

X = -42 /-3

X = 14

3). 5x/2=11/2+7

5x/2 = 11/2+14/2

5x/2=25/2

5x = 25/2 *2

5x = 25

X = 25/5

X = 5

Hope it helps

Answer 2

4+8a=60

8a=60-4

8a=56

a=56/8

a=7

50-3s=8

-3s=8-50

-3s=-42

s= -42/-3

s=14

5x/2-7=11/2

Taking LCM=2

5x/2-14/2=11/2

5x/2=11/2+14/2

5x/2=25/2

5x=25/2×2

5x=25

x=25÷5

x=5
