Answer:
x = 2
Explanation:
You can calculate x in many ways but let see by Subistutition method.
Substitution method is a method that solve one variable interms of other and substitut in other given equetion.
So lets 1st write the equetion solving x and we will sustitute it.
5x - 2y = 4
5x = 4 + 2y
X = (4+2y)/5
now we will sustitute in x of the other equetion .
3x - 4y = -6
3((4+2y)/5 ) - 4y = -6
(12 +6y) / 5 - 4y = -6 ... we will multiply all eq. by 5
5 ( (12+6y) / 5 - 4y = -6 )
12 + 6y - 20y = -30
12 -14y = -30
-14y = 12 -30
-14y = - 18
-14y/-14= - 18/-14
y = 3 so we get y now x
X = (4-2y)/5
X= (4-2(9/7) )/5
X= 2
x = 2 is the solution of X .
