What is the solution to the equation below ?
irina [24]

7/8(x-1/2)= -49/80

Multiply the bracket by 7/8

7/8x-7/16= -49/80

Move -7/16 to other side. Sign changes from -7/16 to +7/16

7/8x-7/16+7/16= -49/80+7/16

7/8x= -49/80+7/16

Find common denominator for 7/16 which is 5. Multiply 5 for the numerator and denominator.

7(5) / 16 (5)

= 35/80

7/8x= -49/80+35/80

7/8x= -14/80

Reduce -14/80 , divide by 2

(-14) /2=7 , 80/2= 40

-14/80= -7/40

7/8x= -7/40

Multiply by 8/7

7/8x*8/7= -7/40 * 8/7

Cross out 7 and 7 , and divide by 7. Cross out -7 and 7 and divide by 7. Cross out 40 and 8 divide by 8.

x= -1/5

Answer: x= -1/5 - G.

X − y = 12<br> x + 2y = 21
olga55 [171]

Answer: x=15, y=3

Step-by-step explanation:

Subtracting the two equations, we get -3y=-9, meaning y=3.

Substituting this into the first equation, we get that x-3=12, and thus, x=15.

Copy and complete the table of each values for each equation
Aleksandr-060686 [28]

Step-by-step explanation:

Given function is y = –x.

Substitute the values of x in the function and find the values of y.

y = –x

At x = –2,

y = –(–2) = 2

At x = –1,

y = –(–1) = 1

At x = 0,

y = –(0) = 0

At x = 1,

y = –1(1) = –1

At x = 2,

y = –(2) = –2

Now, substitute the values of y in the table.

The image of the table is attached below.
