Question

Solve using the substitution method -2x +y=4 y=3x+1​

Answer 1

Answer: (3, 10)

Step-by-step explanation:

X=3 y=10

Answer 2

Answer:

x = 3

y = 10

Step-by-step explanation:

Equation (1) : -2x + y = 4

Equation (2) : y = 3x + 1​

Substitute (2) into (1):

-2x + (3x + 1) = 4

-2x + 3x + 1 = 4

x + 1 = 4

x = 3

Sub x = 3 into (2):

y = 3(3) + 1

y = 10
