Step-by-step explanation:
4x+3y=21
4x+2y=16
If we add both the equation:
4x + 3y = 21
4x + 2y = 16
(-) (-) (-)
-4x - 2y= -16
=> 0+1y= 5
y=5
substituting Y in eq 1
4x+3(5)=21
4x+15=21
4x=21-15
4x=6
x=1.5
Answer:
x= 1.5
do equation 1 and 2 then,
subtract the equation
find the value of y by subtracting
and put the value of y in any equation and get the value of x
