Answer:
x = 3.75
y = 5.5
Step-by-step explanation:
to solve this system of equation using substitution method we would say that
let
y=x+1.75 ............................................. equation 1
4x-2y=4 ............................................. equation 2
substitute equation 1 into equation 2
4x - 2( x + 1.75) = 4
4x - 2x - 3.5 = 4
2x - 3.5 = 4
collect the like terms
2x = 4 + 3.5
2x = 7.5
divide both sides by the coefficient of x which is 2
2x/2 = 7.5/2
x = 3.75
put the value of x into equation 1
y=x+1.75 ............................................. equation 1
y = 3.75 + 1.75
y = 5.5
therefore the value of x = 3.75 and y = 5.5 respectively.
