Do you mean 3x+2=7
3x=7-2
3x=5
x=5 over 3
x=1.6
Assuming the question is: '15 is 250% of what number'.
We can write an equation.
'is' indicates an equal sign
'of' indicates multiplication
'what number' indicates an unknown number we can call 'x'
So we have:
15 = 250% * x
or
15 = 2.5x
Divide 2.5 to both sides:
x = 6
Use distributive property like -20+5h
Answer:
On multiplying the equation by 100 we will get 
Step-by-step explanation:
Given data in the question:-
We have to multiply the equation by 100.
Solution:-
We can write 0.03 as 3/100
Hence the answer is 12-x.
Answer:2
Step-by-step explanation:
Make the numbers whole by multiplying by 15 to both fractions. 4/5 would become 12 and 2/3 would become 10. Subtract 12-10 to get 2.
