First evaluate the value in the parenthesis: (1+2)=3
6/2 is 3
3 times 3 = 9
so the final answer is 9
Answer:
x = -3
Step-by-step explanation:
x is -3 in all values so we just write an equation.
The answers should be the last 2
Slimination
multiply first equaiton by 2
2x+6y=10
add to second equiaotn
2x-2x+6y-6y=10-10
0=0
this is true so therfor they are the same equaiton
so solve
x+3y=5
3y=-x+5
y=-1/3x+5/3
subsituter values for x and get valuse for y
if x=2 then y=1
Answer:
