y is some number and it is equal to -4x+2
y being that same number is also equal to x-3
therefore, we can equate -4x+2 and x-3 to get x-3 = -4x+2
This is the same as starting with y = -4x+2 and replacing the y with x-3
----------------
Let's solve for x
x-3 = -4x+2
x-3+4x = -4x+2+4x .... add 4x to both sides
5x-3 = 2
5x-3+3 = 2+3 .... add 3 to both sides
5x = 5
5x/5 = 5/5 .... divide both sides by 5
x = 1
With this x value, you can now find the y value. Pick any equation that has x and y in it. If we picked the first equation, then
y = -4x+2
y = -4*1+2 ... plug in x = 1
y = -4+2
y = -2
Or we can pick the second equation
y = x-3
y = 1-3 .... plug in x = 1
y = -2

<h3>The solution to the system is (x,y) = (1, -2)</h3>

Answer:
The number is 6.
Step-by-step explanation:
10+(x/2)=13
10+(1/2)x=13
(1/2)x=13-10
(1/2)x=3
(2)(1/2)x=(2)3
x=6
Hello,
dy=cos(x²)*2x *dx

Answer:
-16m + 16n + 77
Step-by-step explanation:
2(m - n) - 18(m - n) + 77
We can let x = (m - n) to make our job easier.
2x - 18x + 77
Now, we can conclude that this expression is equal to -16x + 77.
We can substitute x = (m - n) back into the expression:
-16(m - n) + 77
Distribute:
-16m + 16n + 77
And you're done!

Answer:
since AB and CA is equal, it means that this triangle is an isosceles triangle and that it means that whatever the angle C is, b is also that angle.
so if she is 27 degrees then b is 27° as well
but to find a, you must subtract 180 with the sum of angle b and C
so..
180-(27+27)
180-54
therefore a would be 126°
