Answer:
x = - 6
Step-by-step explanation:
Let x b number, according to instructions´ we must
1.-Multiply by 4
2.-Subtract 6
3.-Divide by 2
4.-Arturo says his new number - 15
4,.Which one was the original number ??
The maths expression for that is :
(4*x - 6 ) / 2 = - 15
we solve for x
4x - 6 = - 30
4x = - 24
x = - 6
360=24%0f x
360=24/100*x
360*100=24x
36000/24=x
therefore, x=1500......
3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
