Solve the system of linear equations by substitution. 2x - y = -4
2x - 2y = -10

Solve the system of linear equations by substitution.
y = 2x
y = 3x - 3

Solve the system of linear equations by substitution.
2x + y = 5
y = x - 5

x= 29/11 or y= 25/11

Step-by-step explanation:

2x - y= 3 equation 1

x + 5y= 14 equation 2

Make x the subject of the formula in equation 2

x= 14 - 5y equation 3

Substitute x=14 - 5y in equation 1

2(14- 5y) - y=3

28 - 10y - y=3

Collect like terms

-10y - y=3 - 28

-11y= -25

divide both sides by coefficient of y

-11y/-11 = -25/-11

y= 25/11

Substitute y= 25/11 in equation 3

x=14 - 5(25/11)

x= 14 - 125/11

x= 29/11
