Answer:
C. (1,-2)
Step-by-step explanation:
The solution to a system of equations is where the graphs intersect.
The graphs intersect where x = -1 and y = -2
Answer:
x=2
Step-by-step explanation:
2x+x+5= 4x+3
first combine like terms, so add 2x and x which is 3x
3x+5= 4x+3
Then subtract 3x from both sides 3x-3x+5= 4x-3x+3
5= x+3
subtract 3 on both sides 5-3= x+3-3
2=x
Answer Check:
substitute x for 2
2(2)+2+5=4(2)+3
multiply 2 times 2 and add 2 which is 6 and 4 times 2 which is 8
4+5= 8+3
add the number to together to see if the two equations are equal
11 = 11
the answer is right
