3n=18
n=6
find the value of z
4 - 6z = 18
4 - 6z = 18
6z=14
z=14/6 = 7/3
find the value of b
7b + 23 = 11
7b + 23 = 11
7b = -12
b= - 12/7
find the value of a
5a + 3 = 2a + 9
5a + 3 = 2a + 9
5a = 2a + 6
3a = 6
a=2
find the value of x
11x - 4= 2x-13
11x - 4= 2x-13
11x=2x-9
9x=-9
x= -1
find the value of y
3y + 4 = 8y - 5
3y + 4 = 8y - 5
3y = 8y -9
y= 5y -9
y= 9/5
find the value of x
