Answer:
x=-7
Step-by-step explanation:
Subtract 5 from both sides.
−x=12−5
Subtract 5 from 12 to get 7.
−x=7
Multiply both sides by −1.
x=−7
The value that would make the ratios equal to 4 to 10... I believe it would be 2 to 5
3d - e = 7d + e = 5 ⇒ 3d - e = 5
7d + e = 5
3d - e = 5
7d + e = 5 +
-----------------------
10d / = 10
10d = 10
d = 10/10
d = 1
7d + e = 5
7×1 + e = 5
7 + e = 5
e = 5 - 7
e = -2
Answer:
x = 2
Step-by-step explanation:
Simplify both sides of the equation.
−20 = − 4x − 6x
−20 = −4x − 6x
−20 = (−4x − 6x)(Combine Like Terms)
−20 = −10x
Flip the equation.
−10x = −20
Divide both sides by -10.
-10x/-10 = -20/-10
x = 2
