Answer:
addition property of equality
Step-by-step explanation:
Given the equation 4(x-5) = -12
Expand
4x - 20 = -12
Add 20 to both sides (addition property of equality)
4x-20+20 = -12+20
4x = 8
x = 8/4
x = 2
Hence the value of x is 2
The justification for step 2 is addition property of equality
It means to Generate something
Answer:
-3x+6
Step-by-step explanation:
-3x-6(-1)
First, multiplying two negatives equals a positive: (-)×(-)=(+). Then,
multiply the numbers -3×+6×1 = -3x+6. Then, you got the answer and the answer is -3x+6
Answer:
Proportion states that the two fractions or ratios are equal
Given the equation:
By cross multiply we get;
Using distributive property;
Subtract 0.4 from both sides we get;
Subtract 1.5x from both sides we get;
Divide both sides by 0.1 we get;
Simplify:
x = 56
Therefore, the value of x that satisfy the equation is, 56
