Substitution to solve the linear system

STALIN [3.7K]

y=4x+2. eq1

y=5x. eq2

4x=2-y

x=(2-y) /4

substitute in equation 2

y=5(2-y) /2

y=(10-5y)/2

4y=10-5y

9y=10

y=10/9

substitute in equation 2 or 1

substituting in equation 2

10/9=5x

x=10/45

x=10/45 y=10/9

you can verify it also.

for the problem 1/5g - 1/10 -g+ 1/3/10g -1/10 tyson created an equivalent expression using the folling steps is his final expres

Leokris [45]

No, Tyson's final expression is not equivalent to the initial expression.

<h3>Fraction addition;</h3>

According to Tyson's evaluation after collecting like terms; we have;

1/5g +(-1g) + 1(3/10g) + (-1/10) + (-1/10)

open parenthesis

1/5g - 1g + 3/10g - 1/10 - 1/10

Upon addition of like terms; we have;

(-1/2)g -1/5.

Hence, the correct expression is; (-1/2)g -1/5
