3x + 4y = 19/3x +6y = 33

(-3,7)

Step-by-step explanation:

These set of problems are called system of equations.

In this case, we can subtract the top equation from the bottom one. Our goal is to get rid of one variable.

3x + 4y = 19

3x + 6y = 33

2y = 14

Do the algebra and all that good stuff =-)

y = 7

Now, we need to substitute y=7 in every equation.

3x + 4(7)=19

Do the multiplication

3x + 28 = 19

3x = -9

x = -3

Great! We got the x value, but we need to plug y=9 into the other equation to make sure our answer is correct.

3x + 6(7) =33

So the multiplication

3x + 42 = 33

3x = -9

x = -3

All these system of equation problems need to be written as an ordered pair.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
