2 answers:
Answer:
10
Step-by-step explanation:
The given expression is
We need to find the coefficient of x.
According to the property of algebra.
In the given expression a=-x and b=5.
Substitute a=-x and b=5 in the above formula.
On further simplification we get
Coefficient of x is a multiplicative factor of x.
Therefore, the coefficient of x is 10.

Step-by-step explanation:
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate
Slope of line
We are given the system of equations -:
Since the second equation is y-isolated equation. It can be substituted as y = 6x+22 in the first equation.
Expand 3 in the expression so we can combine like terms and isolate x-variable.
Then combine like terms.
Get rid of 66 from the left side by subtracting both sides by itself.
To finally isolate the variable, divide both sides by 20 so we can leave x only on the left side.
Simplify to the simplest form.
Normally, we have to find the y-value too but since we only find x-value. The answer is x = -4.
Answer
- x = -4
