Which number from the set {5, 10, 15, 18} makes the equation true?

2x + 3(x + 4) = 37

a)
5

b)
10

c)
15

d)
18

5

Step-by-step explanation:

Given the equation 2x + 3(x + 4) = 37, to find x we will make x the subject of the formula. To do that, we need to first open the bracket of the equation to have;

2x+3x+12=37

5x+12 = 37

Taking +12 to the other side of the equation will change the sign to negative i.e -12 to give;

5x = 37-12

5x = 25

Dividing both sides the coefficient of x which is 5, we will have;

5x/5 = 25/5

x = 5

Since 5 is an element of the given set, 5 is therefore the element of the set that makes the equation true.
