Solve the system of linear equations by elimination. 3x+2y=3 3x−2y=−9

Answer:

x=-1, y=3

Step-by-step explanation:

3x+2y=3

3x-2y=-9

since we have -2y and 2y we can just add the equations

6x=-6

x+0y=-1

x=-1

to solve x using elimination multiply the top equation by -1

-3x-2y= -3

3x-2y=-9

and add

0x-4y=-12

-4y=-12

y=3

and substitute x and y to double; check

3(-1)+2(3)=3

-3+6=3

3=3

checks out so these are correct

Solve the equations
Minchanka [31]

Answer:

#1 - All real numbers are solutions.

#2 - All real numbers are solutions.

Step-by-step explanation:

#1 -

Let's solve your equation step-by-step.

12(6t−4)=3t−2

Step 1: Simplify both sides of the equation.

12(6t−4)=3t−2

(12)(6t)+(12)(−4)=3t+−2(Distribute)

3t+−2=3t+−2

3t−2=3t−2

Step 2: Subtract 3t from both sides.

3t−2−3t=3t−2−3t

−2=−2

Step 3: Add 2 to both sides.

−2+2=−2+2

0=0

Same for #2

consider the function represented by the equation 16b = 4r - 12. write the equation in function notation, where b is the indepen
katovenus [111]

When you write a function in the form y=f(x), y is the dependent variable, and x is the independent variable.

So, if b is the independent variable, it means that we have to solve the expression for r.

To do so, we perform the following steps: start with

16b = 4r - 12

Add 12 to both sides

16b+12 = 4r

Divide both sides by 4:

4b+3 = r

So, we wrote the expression in the form r = f(b) = 4b+3, which means that r is the dependent variable and b is the independent variable, as requested.
