Question

NEED THESE ANSWERED ASAPSolve the inequality and graph its solution:
1.) X-15> 4(-6+3x)
2) 6y-7>y+3

Answer 1

Answer:

(a) $x < \frac{9}{11}$

(b) $y> 2$

Step-by-step explanation:

(1):

$x - 15 > 4(-6+3x)$

Open bracket

$x - 15 > 4*-6+4*3x$

$x - 15 > -24+12x$

Collect Like terms

$x - 12x > 15 - 24$

$-11x > 15- 24$

$-11x > -9$

Divide both sides by -11

$x < \frac{-9}{-11}$

$x < \frac{9}{11}$ --- See first attachment for graph

(2):

$6y-7>y+3$

Collect Like Terms

$6y-y>7+3$

$5y > 10$

Divide both sides by 5

$y > \frac{10}{5}$

$y> 2$ --- See second attachment for graph
