Question

Write the system of linear equations Y=3x+1 Y=2x+3

Answer 1

Answer:

x = 2

y =7

Step-by-step explanation:

the system of linear equation will be solve using substitution method,

let

Y=3x+1.............................................. equation 1

Y=2x+3.............................................. equation 2

substitute equation 1 into equation 2

3x + 1 = 2x + 3

combine the like terms

3x+1 -2x = 3

x = 3 -1

x = 2

put the value of x=2 in either equation 1 or 2

Y=2x+3.............................................. equation 2

y = 2(2) + 3

y = 4 + 3

y = 7
