Answer:
see below
Step-by-step explanation:
a)2x = 10
x = 10/2 = 5
b) 3x = 27
x = 27/3 = 9
a) 5x/2 + 1 = 11
5x + 2 /2 = 11
5x + 2 = 22
5x = 22-2 = 20
x = 20/5 = 4
b)2x/7 - 3 = 2
2x -21/7 = 2
2x - 21 = 14
2x = 14+21 = 35
x = 35/2 = 17.5

Answer:
a) 2x = 10
so, x = 10/2 = 5
b)3x = 27
so , x = 27/3 = 9
c) (5x /2) + 1 = 11
5x/2 = 11-1 =10
5x = 20
x = 20/5 = 4.
d)
2x/7 -3 =2
2x/7 = 2 +3 =5
2x = 7 × 5 = 35
x = 35/2 = 17.5
