8(8 + X) = 16
64 + X = 16
-64 -64
X = -48
Go to sleep buddy or watch a movie
let, x be the no of coins then according to question.Mary have 3x no of coins and John have x no of coins..
now, 3x+x=180
or,4x=180
or,x=180/4
therefore, x= 45
thus mary has 3×45=135 no of coins...
Answer:
x = 5
Step-by-step explanation:
5 - 3x = - 10
<em>Subtract 5 from both sides:</em>
5 - 5 - 3x = -10 - 5
-3x = -15
<em>Divide -3 by both sides:</em>
-3x/-3 = -15/-3
x = 5
hope this helps!! p.s. i really need brainliest :)
