Answer:
x = 7/3
Step-by-step explanation:
To find the of x, isolate it from the other numbers (moving everything to the other side)
What you do to one side, you must do to the other:
3x + 8 = 15
3x + 8 - 8 = 15 - 8 (subtract 8 on both sides to rid of the "+ 8")
3x = 7
3x/3 = 7/3 (divide by 3 on both sides to rid of the 3 attached to "x")
x = 7/3
Answer:
x=2.3
Step-by-step explanation:
15-8=7
Divide 3 on each side (3x=7)7 divided by 3 is 2.3
so X=2.3
