The answer is 18.31 because 55/4 is 13.75
Then 129 degrees minus 90 degrees is 39 degrees so
Hello!
You can put y into one of the equations
4x - 21 = -5x + 24
Add 5x to both sides
9x - 21 = 24
Add 21 to both sides
9x = 45
Divide both sides by 9
x = 5
You can now put x into one of the original equations
y = 4(5) - 21
y = 20 - 21
y = -1
The answer are x = 5 and y = -1
Hope this helps!
The value of x is -2 or negative 2
And the answer for 3x+2 is -4 or negative 4
And 7+(-2)=5
We need a picture of the graph first
