Answer:

x=3

y=-4

Step-by-step explanation:

-7x-2y=-13 ---(1)

x=2y+11

sub (2) into (1), -7(2y+11)-2y=-13

                          -14y-2y-77=-13

                                     -16y=64

                                          y=-4

put y=-4 into (2), x=2(-4)+11

                            x=3

btw, next time, do not use words like(failing,exam,free points,etc in ur caption or content),otherwise,the question would be deleted.

-7x -2y = 13, and then to solve it we put in (2y + 11) where it says x.

So
-7(2y +11) -2y = 13 , then distribute the -7

-14y -77 -2y = 13
-16y -77 = 13
-16y = 64
y = -4

Given the following formula solve for a <br><br>s = a+b+c/2
Hatshy [7]

Answer:

a=2s-b-c

Step-by-step explanation:

Given formula:

s=\frac{a+b+c}{2}

To solve for a

In order to solve for a we will try to isolate a on one side of the equation.

Steps to isolate a.

1) Multiplying both sides by 2 to remove fractions.

2\times s=2\times \frac{a+b+c}{2}

2s=a+b+c

2) Subtracting both sides by b

2s-b=a+b-b+c

2s-b=a+c

3) Subtracting both sides by c

2s-b-c=a+c-c

2s-b-c=a

Thus, we successfully isolated a on one side. The formula for a can be given as:

∴ a=2s-b-c
