Given the numerical expressions:
- 1.) 13/2 + y/3 =2
- Determine the value of y.
2.) Simplify 18x/6
Solution:
- 1.) 13/2 + y/3 =2
In order to find the value of y, transpose 13/2 on the other side of the equation. Note that when transposing a number, the sign changes.
13/2 + y/3 =2
y/3 =2 + 13/2
Change 2 into a fraction in order to add the two values together. 2 is equivalent to 4/2, since 4/2 is equal to 2.
y/3 = 4/2 + 13/2
y/3 =17/2
To get the value of y, we multiply both sides by 3 in order to cancel out y/3.
y/3 (3) = 17/2 (3)
y = 51 / 2
1.) 51/ 2 or 25.5
2.) Simplify 18x/6
In order to simplify the given expression, we simply divide 18x by 6, since 18 is divisible by, this means that it is factorable.
= 18x/6
= 3x
2.) 3x
