Answer:

x = -5

Step-by-step explanation:

Isolate the variable x:

-3x = 15

Since x is being multiplied by -3, we must find a way to cancel it out. To cancel -3 being multipled, divide by -3 instead. Remember, whatever we do to one side of the equation, we must do to the other!

-3x ÷ -3 = 15 ÷ -3

1x = -5

x = -5

Solve the inequality x+1&lt;3/4 and write the solution in interval notation.
Darya [45]

The solution to the inequality in interval form is (-∞, -1/4)

<h3>Inequality expressions</h3>

Inequality are expressions not separates by an equal sign. Given the inequality below;

x+1<3/4

Subtract 1 from both sides to have;

x + 1 - 1 < 3/4 - 1

x < 3/4 - 1

x < (3-4)/4

x < -1/4

Hence the solution to the inequality in interval form is (-∞, -1/4)
