Answer:
First option: 10 - (1) = 9
Second option: 10 - 5 + 4 = 5 + 4 = 9
Step-by-step explanation:
(10 -5) -4 = 5 - 4 = 1
Equivalent equation: 10 - 5 - 4 = 1
10 - (5-4) = there would be 2 ways to do this, you can either solve the equation in the bracket first or break it out. Because the sign before the bracket is minus so when you break it out, the minus sign in the bracket would become -- or equal to +
First option: 10 - (1) = 9
Second option: 10 - 5 + 4 = 5 + 4 = 9

Idk what you r asking help
Answer:
Answer is 1
Explanation:
(-6 + 5) / (-2 + 1)
-1 / -1
1
Y = -2x + 6....so we sub in -2x + 6 for y in the other equation
3y - x + 3 = 0
3(-2x + 6) - x + 3 = 0
-6x + 18 - x + 3 = 0
-7x + 21 = 0
-7x = -21
x = -21/-7
x = 3
now we sub 3 in for x in either of the original equations to find y.
y = -2x + 6
y = -2(3) + 6
y = -6 + 6
y = 0
so ur solution is : (3,0)
