Answer: B
Step-by-step explanation:
7(-2) - 4(1) = -18
-14 - 4 = -18
-18 = -18
TRUE
(-2) + 12(1) = 10
-2 + 12 = 10
10 = 10
TRUE
Answer:
A coefficient is the number that the variable is multiplied by.
The variable is the unknown value, often represented by a letter or symbol.
The constant is the number that is not affected by a variable value, hence the term "constant."
Using the logic above, we can conclude that 4 is the coefficient, x is the variable, and -12 is the constant.

Answer:
x= −3/8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(7x−8x)+6=5(−2−7x)+4
3(7x−8x)+6=(5)(−2)+(5)(−7x)+4(Distribute)
−3x+6=−10+−35x+4
−3x+6=(−35x)+(−10+4)(Combine Like Terms)
−3x+6=−35x+−6
−3x+6=−35x−6
Step 2: Add 35x to both sides.
−3x+6+35x=−35x−6+35x
32x+6=−6
Step 3: Subtract 6 from both sides.
32x+6−6=−6−6
32x=−12
Step 4: Divide both sides by 32.
32x/32= −12/32
x= −3/8
