Question

2x-y=-7 -3x+4y=13

Answer 1

@triggerjoker in the first equation
i.e.
2x - y = - 7
first add y to both the sides
then we get
2x = -7 + y
now add 7 to both the sides
and you get
2x + 7 = y
____________
now place this value of y in the second equation and you would get the value of x
and then place that value of x in the equation ( 2x + 7 = y ) to get the value of y

Answer 2

2x-y=-7 1 eqn ,-3x+4y=13 2 eqn
multiple the first one by 4 which will give you 8x - 4y = -24
