Question

solve 2x +2y=2 and 2x+3y=-8 and hence find the value of m for which y=mx+4​

Answer 1

Answer:

Explanation:

2x + 2y = 2.......i

2x + 3y = -8.....ii

on eliminating i and ii, we have

2x+2y=2 -(2x+3y=-8)

-y=10

y=-10.

substitiute y=-10 in i

2x=12

x=6.

y=mx+4

-10=m(6) +4

m=-14/6

m= -7/3.
