Multiply both sides by 3 to cancel out the 3 in the denominator of the left side of the equal sign. You get:
x + 4 = 18
Now subtract 4 from both sides to get variables one side, constants on the other.
x = 18 - 4
x = 14
Your answer is x = 14

=120
Answer:
a) The difference of a number and six is no less than 15
x - 6 ≥ 15
b) 25 plus a number is at least 13
25 + x ≥ 13
c) g decreased by 25 is at most five
g - 25 ≤ 5
Step-by-step explanation:
a) The difference of a number and six is no less than 15
Let the number be represented by x
We difference is involved in a mathematics question, it requires the application of Subtraction operation, hence:
x - 6 ≥ 15
b) 25 plus a number is at least 13
Let the unknown number be represented by x
When at least is used in Mathematics, is means greater than or equal to a particular value,
Hence,
25 + x ≥ 13
c) g decreased by 25 is at most five
At most means less than or equal to a particular value, hence:
g - 25 ≤ 5
X+y = 6
x-y = 2
Add both equations,
2x = 8
x = 4
Substitute it in equation 1,
4+y = 6
y = 6-4 = 2
In short, x = 4 & y = 2
Hope this helps!
The answer is 24. I believe.
