Question

solve by substitution method 3x+2y-7=0,4x+y-6=0

Answer 1

Answer:

x = 1, y = 2

Step-by-step explanation:

3x + 2y - 7 = 0. ------------(1)

4x + y - 6 = 0

8x + 2y - 12 = 0. ---------(2)

Subtracting equ.1 from 2

8x + 2y - 12 - 3x - 2y + 7 = 0 - 0

5x - 5 = 0

5x = 5

x = 1

Putting x = 1 in equ.1

3(1) + 2y - 7 = 0

3 + 2y - 7 = 0

2y = 4

y = 2

Plz mark me as the brainliast.
