If they both are equal to y, they must be equal to each other therefore,
6x-7 = 3x+11
3x = 18
x=6

Find the solution set. (x+7)(x+7)=0
levacccp [35]

For this case we must find the solution of the following expression:

(x + 7) (x + 7) = 0

If we isolate a term and we equate to zero, we have:

x + 7 = 0

Subtracting 7 on both sides of the equation we have:

x + 7-7 = 0-7\\x = -7

Thus, the solution of the expression is given by:

x = -7

ANswer:

x = -7

X-4y=-12

eliminate y's
multily 2nd equaiton by -4 and add to top one

x-4y=-12
<u>-16x+4y=-48 +
</u>-15x+0y=-60

-15x=-60
divide both sides by -15
x=4
sub back
x-4y=-12
4-4y=-12
minus 4 both sides
-4y=-16
divide both sides by -4
y=4

x=4
y=4

Answer:

45

Step-by-step explanation:

You already solved that the 2 angles of the triangle are 55° and since all of the angles are on a straight line, they add up to 180°

and the equation becomes...

3x-10+55=180

3x+45=180

Subtract 45 from both sides

3x=135

Divide by 3

x= 45

Then to double check you plug 45 as the value of x in.

3(45)-10+55=180

135-10+55=180

125+55=180

180=180
