Answer:

y = - x + 8

Step-by-step explanation:

Step 1:

y = mx + b     Slope Intercept Form

Step 2:

y = -x + b     Input Slope

Step 3:

7 = - 1 ( 1 ) + b    Input x and y

Step 4:

7 = - 1 + b      Multiply

Step 5:

b = 8     Add 1 on both sides

Answer:

y = - x + 8

Hope This Helps :)

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.
lyudmila [28]

Answer:

-\frac{21}{2}

Step-by-step explanation:

We can solve this system just by summing each side of the equation:

So, both left sides will be sum, and both right sides too.

The resulting expression will be:

(3-y)+(3-y) = 6+21

Ordering and solving both sides:

6-2y=27\\-2y=27-6\\y=\frac{21}{-2}

Hence, the value to the system is -\frac{21}{2}

It's important to combine both equation, because the exercise is asking for the solution of the system.

The equation 3x + 2 = 29 is modeled below.
DanielleElmas [232]

Answer:

Subtract 2 from both sides.

Step-by-step explanation:

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

> Also, note the equal sign, what you do to one side, you do to the other side of the equation.

First step is to subtract 2 from both sides of the equation:

3x + 2 (-2) = 29 (-2)

3x = 29 - 2

3x = 27

The second step is to divide 3 from both sides of the equation:

(3x)/3 = (27)/3

x = 27/3

x = 9
