How too work this out

Mathematics
1 answer:
Oduvanchick [21]3 years ago
4 0

Answer:

x = 4

Step-by-step explanation:

\frac{7 + 2x}{3} = 5

Multiply both sides of the equation by 3

7 + 2x = 15

Subtract 7 from both sides of the equation

2x = 8

Divide both sides of the equation by 2

x = 4

Hope this helps :)

X + y = 5 ; x - y =3 solve using linear combination
Bas_tet [7]

Answer:

x = 4

y = 1

Step-by-step explanation:

use one equation to solve for one variable.

y = 5 - x

Now plug the value of y in the other equation

x - (5-x) = 3

x+x= 3+5

2x=8

x=4

Now use the value of x to find the value of y on the first equation

y = 5 - x

y = 5 - 4

y = 1
