Explanation:
Given,
-2x + 3y = -9 ------- (eqⁿ 1)
4x - 6y = 2 ----------- (eqⁿ 2 )
now,
multiply eqⁿ 1 by 2
so we got,
-4x + 6y = -18 -------- (eqⁿ 3)
now,
subtract eqⁿ 2 from eqⁿ 3
we got,
-8x = -16
x = -16/-8
x = 2,
so , after putting values in the eqⁿ 2
we got,
4(2) - 6y = 2
8 - 6y = 2
6y = 2 - 8 = 6
y = 6/6
y = 1
x = 2 and y = 1
hope this answer helps you dear...take care!
