Multiply each equation by a constant that would help to eliminate the y terms. 2x-5y=-21
3x-3y=-18
What are the resulting equations?
6x- 15y =-63
-15%+ 15y = 90
6x- 15y-63
1-15x+ 15y=90
6x-15y=-63
-15%+ 15y = -90
6x + 15y = -63

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

step-by-step explanation:

just get this app called photo math it should be able to do those

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
