solve the equation:y+2/3+y-3/4=7-y-1/2
Answers
Answer:
Simplify given equations
7(y+3)−2(x+2)=14
or 7y−2x=−3
and 4(y−2)+3(x−3)=2
or 4y+3x=19
new set of equations is :
7y−2x=−3...(1)
4y+3x=19...(2)
Let us use the elimination method to solve the given system of equation.
Multiply (1) by 3 and (2) by 2. And add both the
equations.
Adding
29y=29⇒y=
29
29
=1
21y−6x=−98y+6x=38
Substitute the value of x in equation (1), we have
7(1)−2x=−3
x=5
Answer: x=5 and y=1
