10 x 42x - 18 = 2082

1 answer:

4 0

Hey, I am able to help you today :)

Step 1 - Simplify:
420x^2 - 18 = 2082

Step 2 - Add 18 to both sides:
420x^2 = 2082 + 18

Step 3 - Simplify 2082 + 18 to 2100:
420x^2 = 2100

Step 4 - Divide both sides by 420:
x^2 = 2100/420

Step 5 - Simplify 2100/420 to 5
x^2 = 5

Step 6 - Simplify:
x = 5

Step 7 - Check your answer:
10 x 42 x 5 - 18 =2082

Hope this helps you today :)
