Show the steps of solving. a) 6x - 2y = 28 4x + 2y = 12

PLEASE HEL I’ll give brainlist!!!

x = 4 and y = -2

Step-by-step explanation:

Let 6x - 2y = 28 be equation (i)

and 4x + 2y = 12 be equation (ii)

To solve the following equations, first add the equations:

6x - 2y + 4x + 2y = 28 + 12

6x + 4x + 2y - 2y = 28 + 12

10 x = 40

x = 4

Substituting in (ii)

4x + 2y = 12

4*4 + 2y = 12

2y = 12 - 16

2y = -4

y = -2
