[ 2,-3,4,-1] - [-2,7,11,0]=[a, b,c, d]

  [4, -10, -7, -1] = [a, b, c, d]

Step-by-step explanation:

Operations of addition and subtraction on lists are generally performed term by term.

  [2-(-2), -3-7, 4-11, -1-0] = [a, b, c, d]

  [4, -10, -7, -1] = [a, b, c, d]

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
