solve the system of equations using the substitution method:

y=2+1/4x
3x−5y=-3

solve for
x:
y:

Step-by-step explanation:

Whenever one of the equations gives an expression for one of the variables, it is useful to use that expression to substitute into the other equation.

Using the expression for y and substituting into the second equation, we have ...

  3x -5(2 +1/4x) = -3

  3x -10 -5/4x = -3 . . . . . . eliminate parentheses

  7/4x = 7 . . . . . . . . . . . . . add 10, collect terms

  x = 4 . . . . . . . . . . . . . . . . .multiply by 4/7

  y = 2 + (1/4)(4) = 3

The solution is (x, y) = (4, 3).
