Answer:
x = -3
Step-by-step explanation:
2x + y = -2
4x + y = -8
2x + y = - 2
y = -2x - 2
4x + y = - 8
y = -4x - 8
y = -2x - 2
y = -4x - 8
-2x - 2 = -4x - 8
4x - 2x = 2 - 8
2x = -6
2x/2 = -6/2
x = -3
To check just use da graph ;w;
The x is -3
Answer:
x=5
Step-by-step explanation:
∠D=∠E (angles opposite to equal sides are equal)
So,
=3x+10
10=
-3x
10=x(x-3)
we know 5×2= 10 & 5-3=2,
So, 10=5×(5-3)
10=5×2
∴x=5
