Answer:
y = 0
Step-by-step explanation:
Substitute x into the equation, then solve for y:
y + 4 = 2(3 - 1)
y + 4 = 2(2)
y + 4 = 4
y = 0
Answer:
170
Step-by-step explanation:
16) First solve like a normal equation.
3|x/9| - 1 = 2
3|x/9| = 3
|x/9| = 1
Now just separate into two equations:
x/9 = 1
x/9 = -1
So x = 9, -9
17) Solve like normal:
-4 - 2|b - 10| = -6
-2 |b - 10| = -2
|b - 10| = 1
Now just separate into two equations:
b - 10 = 1
b - 10 = -1
So then b = 11, 9
Answer:
The coefficient of variable term y is -1
Step-by-step explanation:
We have an expression given in the question that is:
6 - y + 3
We have to find the coefficient of the variable term.
In mathematics, variable can be defined as any term which is to be measured. For example in the given expression, y is the variable because its value is unknown yet and it has to be measured.
Coefficients are the number the multiply the variable
For example
In 2x, x is the variable and 2 is the coefficient.
Now in the given expression, we have
6 - y + 3
or
6 + (-1)(y) + 3
So considering (-1)(y), the variable is y while its coefficent is -1
