Answer:
X=3 and y= -6
Step-by-step explanation:
Let's solve your system by substitution.
2x−y=12;5x+3y=−3
Step: Solve. 2x−y=12for y:
2x−y=12
2x−y+−2x=12+−2x(Add -2x to both sides)
−y=−2x+12
−y= -2x+12
−1= −1. (Divide both sides by -1)
y=2x−12
Step: Substitute 2x−12 for y in 5 x+3y=−3:
5x+3y=−3
5x+3(2x−12)=−3
11x−36=−3 (Simplify both sides of the equation)
11x−36+36=−3+36(Add 36 to both sides)
11x=33
11x= 33
11. 11(Divide both sides by 11)
x=3
