Answer:
x = 6
y = -9
Step-by-step explanation:
we have:
7x +2y = 24 equation 1
8x+2y= 30 equation 2
using equation 2 we have:
8x = 30 -2y
x=
equation 3
using equation 3 in equation 1 we have:
7()+2y = 24
so we have:
x=
x=
x=6
Answer: points for points
Step-by-step explanation:
Hi t sure what to do?
X2 + 12 = 7x x2 – 7x + 12 = 0factor the equation (x – 3 ) ( x – 4 ) = 0 Then equating both factor to 0 X – 3 = 0 X = 3 And X – 4 = 0 X = 4 So the answer is X = 3 X =4
A triangle always adds up to 180 degrees:
Therefore, 48 + 6x + 9x-3 = 180
Solve for x:
180 - 45 = 15x
135 = 15x
x = 9 degrees
