Answer:
x = 24
Step-by-step explanation:
Firstly, isolate x by adding 2 to both sides.
9 = 3/8x
Then, multiply 8 to both sides.
72 = 3x
Then, divide both sides by 3.
24 = x
7=3/8x-2
move -2 to the other side
sign changes from -2 to +2
7+2=3/8x-2+2
7+2=3/8x
9=3/8x
multiply both sides by 8/3 to get x by itself
9(8/3)=3/8x(8/3)
pretend that 9 has a denominator which is 1
cross out 9 and 3, divide by 3 and then becomes 3*8=24
answer:
x=24
