    x=0.3

    y=1.6

    Step-by-step explanation:

    To solve this question we will have to use substitution method

    Substitution method is when a certain number is given in replace to a given letter

    Back to the question

    y=2x+1 ... (2)

    4x+3y=6 ... (1)

    Let's substitute the value of y into (1)

    4x+3 (2x+1) = 6

    4x+6x+3=6

    Let's collect like terms

    4x+6x=6-3

    10x=3

    Divide both sides by 10

    x=0.3

    Let's substitute the value of x into (2)

    y=2 (0.3) + 1

    y=0.6+1

    y=1.6

    Therefore x is 0.3 and y is 1.6
