1.5b=2
b=1.3 repeating or 1 1/3
First you have to rewrite the equation:
(x ÷ 4) + 8 = 38
Second you have to write the division as fraction:
(¼x) + 8 = 38
Third you have to take off the unecessary bracket:
¼x + 8 = 38
Fourth multiply 8 and 38 by 4
x + 32 = 152
Fifth step move the constant to the right hand and change the sign.
x = 152 - 32
Then subtract:
x = 120
