3x+y=4
2x+y=5
solve using linear combination

Answers

Idk what linear combination is but you can solve this way:
3x+y=4
-2x-y=-5
x=-1
3(-1)+y=4
-3+y=4
y=7
So x=-1 and y=7

Answer:

(-1,7)

Step-by-step explanation:

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

Given: m∠QVR = 49°

Prove: x = 15

Answers

Answer:

see the procedure

Step-by-step explanation:

The picture of the question in the attached figure

we know that

m\angle QVR=m\angle TVU ----> by vertical angles

substitute the given values

49^o=(3x+4)^o

solve for x

subtract 4 both sides

3x=49-4\n3x=45

divide by 3 both sides

x=45/3\nx=15

Answer:

the reason for 4 -> vertical angles theorem

3x + 4 = 49 is the answer for the other one

Step-by-step explanation:
