Plz help with my math!

Answer 1

Answer:

(-2, 6)

Step-by-step explanation:

Plug in one of the equations into the y-variable (doesn't matter which):

2x + 10 = -4x - 2

Combine like terms by adding the 4x to both sides. This makes it cancel out on the right side, and 2x + 4x on the right side is 6x:

6x + 10 = -2

Combine like terms by subtracting 10 from both sides, making it cancel out on the left side, and on the right: -2 - 10:

6x = -12

Then isolate the x-variable by dividing both sides by 6:

x = -2

Taking the -2, plug it into an x-variable in either of the equations:

y = 2x +10

y = 2(-2) + 10

y = -4 + 10

y = 6

Answer 2

Answer:

the required coordinates is : -

(-2 , 6)

Step-by-step explanation:

here's the solution: -

=》y = 2x + 10

=》y = -4x - 2

by equating the above equations, ( since, y = y )

we get ,

=》2x + 10 = -4x - 2

=》2x + 4x = -2 - 10

=》6x = -12

=》x = -12 ÷ 6

=》x = -2

now, plugging the value of x as -2 in equation 1,

=》y = 2x + 10

=》y = (2 × -2) + 10

=》y = -4 + 10

= 》y =6
