Answer:
(x,y)=(2,-3)
Step-by-step explanation:
6x+2y=6
7x+3y=5
Multiply both sides by 3
18x+6y=18
7x+3y=5
Multiply both sides by -2
18x+6y=18
-14x-6y=-10
Eliminate one variable by adding the equations
4x=8
x=2
Substitute the value of x to get y
6(2)+2y=6
y=-3
x=2
y=-3
Answer:
Step-by-step explanation:
<A = 180 - (63+90)
<A = 180 - 63 - 90
<A = 180 - (63+45+<B )
<A = 180 -63 -45 -<B
The communicative property means that multiplied numbers can be multiplied in any order.
3*2*4 is the same as 2*4*3. The answer will be the same.
So (24 * x) is the same as (x * 24).
