Question

Algebra 1B. How many solution does the system have?
2x=-10y+6 and x+5y=3

Answer 1

x+5y=3;2x=−10y+6
Step: Solvex+5y=3for x:
x+5y+−5y=3+−5y(Add -5y to both sides)
x=−5y+3
Step: Substitute−5y+3forxin2x=−10y+6:
2x=−10y+6
2(−5y+3)=−10y+6
−10y+6=−10y+6(Simplify both sides of the equation)
−10y+6+10y=−10y+6+10y(Add 10y to both sides)
6=6
6+−6=6+−6(Add -6 to both sides)
0=0
