Solve for y:-

y - 18 = 10

y = ?

Thank You!

Answers

In this question we can seethat there is one unknown variable named “y” and one equation. So it isabsolutely possible to find the correct value of the unknown variable “y”. Nowlet us check the equation that is given and solve it correctly.
y - 18 = 10
y = 10 + 18
  = 28
So the value of the unknown variable “y” is 28. I hope thisis the answer you were looking for and the procedure is clear to you.
To solve for y we will use the INVERSE OPERATION of subtraction which is addition. Lets do it:-

y - 18 = 10
10 + 18 = y
10 + 18 = 28
y = 28

CHECK OUR WORK:-

28 - 18 = 10
We were RIGHT!!!

So, y = 28.

Hope i helped ya!!! 

Which expression has a value of 1? A.
4 ÷ 4 + 4 – 4


B.


4 · 4 – 4 ÷ 4


C.
4 – 4 ÷ 4 – 4


D.
4 ÷ 4 + 4 + 4

Answers

I am adding the brackets to show in which order the expressions will be evaluated:
A.
(4 ÷ 4) + 4 – 4 = 1+4-4 = 1 (the correct answer)

B.
(4 · 4) – (4 ÷ 4)= 16-1 = 15

C.
4 –( 4 ÷ 4) – 4= 4-1-4 = -1

D.
(4 ÷ 4) + 4 + 4 = 1+4+4 =9
A is the answer because 4 divided by 4 plus 4 minus 4 =1
