Yes because it is linear, also if you set up the proportion 2/4=1/2 they are equal.
Answer:
x = 5
y = 2
Step-by-step explanation:
-3x + 3y = -9
3y = 3x - 9
Equation 1. <em><u>y = x - 3</u></em>
-3x + y = 7
Equation 2. <u><em>y = 3x + 7</em></u>
So, put number 1 equation to number 2's y :
x - 3 = 3x + 7
x -3x = 7 + 3
-2x = 10
2x = 10
x = 10/2
x = 5
And, put x, which is 5 , to the any equation to figure out the y.
This time, I'll use equation number 1.
y = 5 - 3
y = 2
Answer: i dont know but thanks for the points
Step-by-step explanation:
First part: 6 x573= 6 x(500+70+3)
Explanation: Break 573 into expanded form and multiply each place value by 6.
Second part: (6x500)+(6x70)+(6x3)
Explanation: Use the distributive property.
Third part: 3000+420+18= 3438
Explanation: Solve the equations you made in part 1 & 2.
