Answer:
The answer to number 3 would be 6 on the number line, open circle, and then a line dashed to 42, and 4 on the number line, closed circle, and a closed line to 7.
The answer to number 4 would be -8 on the number line, open circle, and then a line dashed to 2, and 9, open circle closed line to 81.
Answer:
Use y + x = 3 and solve for either x or y.
Step-by-step explanation:
Substitution is a method to solve a system of equations by substituting an expression from one equation into the other.
To begin, first solve one equation by isolating for one variable. Choose the equation which will have the least number of steps to do so.
y + x = 3 can be solve for x or y by subtracting the other variable. Since this only requires one step use this equation. Either variable can be used.
The answer is a I believe
Ok you need to do y-(-2) over -3-(-9) and you get(y+2)/(-3+9)=1
so y+2=1*6
y+2=6
y=4
<u>ANSWER:
</u>
The value of x after evaluating the given equation x + 6 - 5 = 8 - 2 is 5.
<u>SOLUTION:
</u>
Given, equation in one variable is x + 6 – 5 = 8 – 2
And, now, we have to find the value of the variable x in the equation by solving the given equation.
So, let us solve the given equation for x.
Then, x + 6 – 5 = 8 – 2
x = 8 – 2 – (6 – 5) [sending all the numerical terms on left side to the right side.
x = 8 – 2 – 6 + 5
x = 8 + 5 – 2 – 6
x = 13 – 8 = 5
Hence, the value of x after evaluating the given equation is 5.
