mam but i did not got my answer which i was asking for
you didn't give any equations
sorry mam it was my fault.
just wait a sec
y-7x+42=0
y-3x-6=0
Step1: Substitute7x−42foryin−3x+y−6=0:
−3x+y−6=0
−3x+7x−42−6=0
4x−48=0(Simplify both sides of the equation)
4x−48+48=0+48(Add 48 to both sides)
4x=48
4x4=484(Divide both sides by 4)
x=12
Step: Substitute12forxiny=7x−42:
y=7x−42
y=(7)(12)−42
y=42(Simplify both sides of the equation)
Answer:
x=12 and y=42
−3x+y−6=0
−3x+7x−42−6=0
4x−48=0(Simplify both sides of the equation)
4x−48+48=0+48(Add 48 to both sides)
4x=48
4x4=484(Divide both sides by 4)
x=12
Step: Substitute12forxiny=7x−42:
y=7x−42
y=(7)(12)−42
y=42(Simplify both sides of the equation)
Answer:
x=12 and y=42
Thank you mam.
