Question

Write and solve an equation using the descriptions below.

The sum of 4 and three times a number is 19

Answer 1

4+3x=19 so, x=5

19-4= 15, 15/3=5 or 5*3=15, 19-15=4.

good luck

Answer 2

5

Explanation:

Let x be that number.

4 + 3 × x = 19

4 + 3x = 19

Add -4 on both sides.

4 + 3x - 4 = 19 - 4

3x = 15

Divide both sides by 3.

(3x)/3 = 15/3

x = 5
