Question

find whether x=-2 is the solution of the linear equation 3+2x=-1
do it step by step ​

Answer 1

Answer:

Step-by-step explanation:

if x= -2, then..

3 + 2 (-2) = lets take z

so,

z = 3 + 2 x (-2)

z = 5 x (-2)

z = -10

[given = 3 + 2x = -1]

since -10 is not equal to -1

therefore it is FALSE!
