Solve -2x+3y=-9 4x-6y=2

mr Goodwill [35]

Step-by-step 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!
