If x=6, how do I find y?

Mathematics
1 answer:
Fantom [35]4 years ago

Answer:

y = 35

Step-by-step

(5x - 20) + (5x +4y) = 180

Replace x with 6.

(30-20) + (30 + 4y) = 180

10+30+4y = 180

40+4y = 180

4y = 180-40

4y = 140

y = 35

Solve using substitution for x and y 5x+y=16 <br> y=2-3x
valentina_108 [34]

Answer:

X = 7   Y = -19

Step-by-step explanation:

If you want to solve this equation by substitution then you have to put the second equation in, so it will look something like this

5x + 1(2-3x)=16

Apply distributive property to solve.

Once you find x, plug it in to find y

To double check your work, you can plug the coordinated values back in

-19 = 2 - 3(7)

-19 = 2-21

This is true, so our solution is correct.

Hope this helps :)

. A family spends 1/10 of its annual income for housing, 1/4 for food and clothing, 1/5 for general expenses, and 2/15 for enter
IrinaVladis [17]
First you have to set the fractions with an equal denominator
hint: numerator/denominator
all of the denominators go into sixty

1/10=6/60
1/4=15/60
1/5=12/60
2/15=8/60

then you will have to add the numerators
(6+15+12+8)/60 = 41/60
simplify if possible but it's not necessary for this one
