Answer:

Step-by-step explanation:

If denominators are same, subtract the numerators.For example

6/8-1/8 here denominators for both fractions are same (8)

6-1/8 = 5/8

If denominators are different, find LCM for the denominators.

1/2 - 1/3 .Here LCM for 2 and 3 is 6

1*3/2*3 - 1*2/3*2 = 3/6 - 2/6 { now same denominator 6}

=(3-2)/6=1/6

1/2 (3/2 y + 1/3) = -1/2 (y- 5/2)

dem82 [27]

1/2 [ (3/2)y + 1/3] = -1/2 [y-5/2]

(3/2)y + 1/3 = -(1/2)y + 3

(3/2 + 1/2)y = 3 - 1/3

2y = 8/3

y = 4/3

y = 1.33

How many solutions can be found for the equation 4z + 2(z - 4) = 3z + 11

Gnom [1K]

4z+2(z-4)=3z+11 perform indicated multiplication on left side

4z+2z-8=3z+11 combine like terms on left side

6z/-8=3z+11 add 8 to both sides

6z=3z+19 subtract 3z from both sides

3z=19 divide both sides by 3

z=19/3

z=6 1/3

So there is only one solution when z=6 1/3

How many is 7= 12 + 5h With procedure

Arlecino [84]

H= -1 here's why:

7 = 12 + 5h

First you subtract 12 from both sides then the equation would look like:

-5 = 5h

Then you would divide the equation by 5 from both sides it would then look like:

-1 = h
