What is the solution of the system? use substitution.

3x + 2y = 7
y = –3x + 11
a.
(6, -3)

b.
(6, -7)

d.
(5, -4)

Hi Brainiac

3x+2y=7

y=-3x+11

We need to solve y=-3x+11 for y

Now let's start by substitute -3x+11 for y in 3x+2y=7

3x+2y=7

3x+2(-3x+11)=7

-3x+22=7

Now add -22 to both sides

-3x+22-22=7-22

-3x=-15

To find the value for x we need to divide both sides by -3

-3x/-3= -15/-3

x=5

Now we have the value for x :)

Let's find the value for y by substitute 5 for x in y=-3x+11

y=-3x+11

y=-3(5)+11

y=-4

Here you go :)

The answer is D

Good luck :0

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
