Answer:
x = 0,3
Step-by-step explanation:
y-10x=5 move -10x to the other side to get y by itself
y=10x+5 then you would substitute this equation into the other equation where you see y
10x+5=x^2+7x+5 move everything to one side
0=x^2+7x+5-10x-5 combine like terms
0=x^2-3x factor
0 = x(x-3) set each equal to zero
x=0
x-3 = 0 add 3 to both sides
x = 3
the answer is x=0 and x=3
