Answer:

x = 3

Step-by-step explanation:

Step 1: Distribute

42 + 3x = 57

Step 2: Subtract 42 on both sides

3x = 15

Step 3: Divide both sides by 3

x = 3

And we have your answer!

Answer:

x=5

Step-by-step explanation:

First multiply 3(14+x) = 42 + 3x

Now you have the equation 42 + 3x =57

Then subtract 42 from both sides

The equation would be 3x = 15

Divide 3 from each side to get the x value

15/3=5

So therefore your answer would be x = 5

Hope this helps!

-{1-2[10-(-1-5)²]}<br><br> ASAP<br><br> I got -53 is it right?
Sauron [17]

Answer:

You are correct the answer is -53

Step-by-step explanation:

So you first add -1 and -5

Which is -6

-6 to the second power is 36

36 times - is -36

10-36 is -26

Then it is multiplied by -2

Thus 52

Add 1 to 52 which is 53

53 times - is -53

Thus you are correct
