Answer:

x = -10

y = 1

Step-by-step explanation:

x - 5y = -15

x - 2y = -12

__________--

-3y = -3

y = -3/-3

y = 1

x - 2y = -12

x - 2(1) = -12

x - 2 = -12

x = -12 + 2

x = -10

Answer:

If solving for X. (didn't know if you were solving for X or Y.

x=2y-12

x=5y-15

Step-by-step explanation:

x-2y=-12

+2y on both sides

x=2y-12

x-5y=-15

+5y on both sides

x=5y-15

U will be made brainiest if this answer is right
Daniel [21]

Answer:

x= -7

Step by Step Explanation:

We can write them both like functions like this

A= 5x- 4

B= 3x+ 8

The output of A will be three times the output of B

A=3b

We replace with the functions

5x-4= 3

We solve for x

5x= -4= 9x + 24

5x- 9x= 24 + 4

-4x= 28

x= 28 - 4

x= -7

The output that makes the out put of A 3 times the output of B is -7

Hope it helped

Triangle ABC is similar to triangle LMN by the similarity postulate
likoan [24]

Answer:

Same as Angle B. 90 degrees.

Step-by-step explanation:

If triangles are similar then they have the exact same angle measures. Angle m will have the same value as angle B. If angle B's measure is not found, then find it by adding angle A and angle C together and subtract from 180.

The picture is cut off but if A =60 and C=30 then 60+30=90 and 180-90=90. Angle B and M are both 90 degrees.
