Question

a)find the value of k if x=-2and y=-1 is a solution of the equations 2x+3y =k
b)check whether i)(√2,4√2) ii)(4,-1) are solution of the equations x=2y=6

​

Answer 1

A. 2x(-2) + 3x(-1) = k
-4 - 3 = k
-7 = k
B. i) x-2y =6
√2 -2x 4√2 =6
√2-8√2 = 6
√2- 16 =6
6=6
ii). X-2y=6
4=2x(-1)= 6
4-(-2) =6
6=6
