Answer:
y=3
x=-4
Step-by-step explanation:
-x+2y=10
*3
-3x+6y=30,
then add it with 3x+5y=3,
3x+5y=3
-3x+6y=30, would be...
0x+11y=33,
y=3,
x=-4
x^2+7x-30=0 Rewrite the expression.
x^2+10x-3x-30=0 Factor the expressions.
x(x+10)-3 (x+10)=0 Factor the expression.
(x+10)(x-3)=0 Separate into possible cases.
x+10=0
Solve.
x-3=0
x1= -10
x2= 3
