X-30+x-30+x=180
3x-60=180
3x=240
X=80
Answer:
no solution
Step-by-step explanation:
(you do the exact same you'd do in an equation problem. Get x by itself)
3x+1<2x-2<5x+7
1 < -x-2 < 5x+7
3< -x < 5x+9
3 < -6x < 9
-(1/2) > x > -(3/2)
x can't be bigger than -3 halves and be smaller than -1 half, so the answer is no solution
