Question

3•(93-x)=57 как решать???

Answer 1

93-х=57:3 93-х=19 Х=93-19 Х=74

Answer 2

3•93 - 3x = 57

279 - 3x = 57

-3x = 57 + 279

-3x = 336

3x = -336

x = -112

Answer 3

To solve the equation 3•(93-x) = 57, follow these steps:

Step 1: Distribute the 3 on the left side of the equation. 3•(93 - x) = 3 • 93 - 3 • x = 279 - 3x

Step 2: Now, the equation becomes: 279 - 3x = 57

Step 3: Isolate the variable (x) on one side of the equation. To do this, move the constant term (57) to the other side by adding 57 to both sides of the equation.

279 - 3x + 57 = 57 + 57

Simplify:

279 - 3x + 57 = 114

Step 4: Next, combine the constant terms on the left side:

279 + 57 - 3x = 114

Step 5: Subtract 279 + 57 from both sides to isolate the term with the variable (3x) on one side.

279 + 57 - 279 - 57 - 3x = 114 - 279 - 57

Simplify:

-3x = -222

Step 6: Finally, solve for x by dividing both sides of the equation by -3:

x = -222 / -3

Simplify:

x = 74

So, the value of x that satisfies the equation is x = 74.
