The solution of the given equation (x + 5) - ( 2x - 3) = 6 is 2.
<h3>What is a linear equation?</h3>
A linear equation is an equation that has the variable of the highest power of 1.
The standard form of a linear equation is of the form Ax + B = 0.
The given equation is;
(x + 5) - ( 2x - 3) = 6
To solve;
(x + 5) - ( 2x - 3) = 6
Distribute the negative;
(x + 5) - 2x + 3 = 6
we need to get the like terms together;
x - 2x + 5+ 3 = 6
-x + 8 = 6
Subtract 8 from both sides, we get;
-x = -2
x = 2
Hence, the solution of the given equation is 2.

9 x 2 = 18
Answer:
Step-by-step explanation:
A group of 2 hot dogs and 1 soda makes a group of 3 items. There were ...
234/3 = 78
groups of items sold.
Since there is 1 soda in the group, that's 78 sodas. The number of hot dogs is 2 times that, or 156 hot dogs.
78 sodas and 156 hot dogs were sold.
Oldest = 2x
Middle = x + 5
Youngest = x
2x + x + 5 + x = 57
combine like terms
4x + 5 = 57
subtract 5 from both sides
4x = 52
divide both sides by 4 to isolate x
x = 13
Oldest = 2x = 2(13) = 26
Middle = x + 5 = 13 + 5 = 18
Youngest = x = 13
Answer:
3 3/5
Step-by-step explanation:
Raphel bought 2 1/2 pounds of chicken for $9
Therefore the cost per round of the chicken can be calculated as follows
9÷5/2
= 9×2/5
= 18/5
= 3 3/5
