Four times the number of coins in my pocket plus five more is twenty-nine. Write an equation for the number of coins in my pocke
Lynna [10]
There are six coins already in pocket, but let’s say we don’t know it.

We would figure it out by reversing the problem. Let’s start with twenty-nine. We would subtract 5, because we are reversing. Now we have 24. Now, let’s divide by four. We would get 6.

A simpler answer would be 29 - 5 [divided by] 4 = [answer]

Please help, i would really appreciate your help
otez555 [7]

Answer:

x = 7

Step-by-step explanation:

Since the lines are parallel, we know that the two angles are equal. So you can write (7x - 4) = (5x + 10). Then you just solve for x.

7x - 4 = 5x + 10

add 4 from both sides to get

7x = 5x + 14

subtract 5x from both sides to get

2x = 14

divide both sides by 2 to get

x = 7
