User: How do I solve this problem of 3x + 4 = 19?

Weegy: Solution: 3x+6?15 First, let's work on the left hand side of your inequality, the 3x+6 This means, for instance, [ to see if it can be simplified at all. Multiply x and 3 Multiply x and 1 The x just gets copied along. The answer is x x 3*x evaluates to 3x 3*x+6 evaluates to 3x+6 So, all-in-all, the left hand side of your inequality can be written as: 3x+6 Now, let's work on the right hand side of your inequality, the 15 The right hand side of your inequality can be written as: 15 So with these (any) simplifications, the inequality we'll set out to solve is: 3x+6 ? 15 Move the 6 to the right hand side by subtracting 6 from both sides, like this: From the left hand side: 6 - 6 = 0 The answer is 3x From the right hand side: 15 - 6 = 9 The answer is 9 Now, the inequality reads: 3x ? 9 To isolate the x, we have to divide both sides of the inequality by the other "stuff" (variables or coefficients) around the x on the left side of the inequality. The last step is to divide both sides of the inequality by 3 like this: To divide x by 1 The x just gets copied along in the numerator. The answer is x 3x ? 3 = x 9 ? 3 = 3 The solution to your inequality is: x ? 3 So, your solution is: x must be less than 3 ]

3x + 4 = 19

3x = 19 - 4

3x = 15

x = 15/3

x = 5
