You can verify that your answer is a solution to the original equation by checking if Testing what what testing is a true statement. Which property of equality allows you to do this? A reflexive B transitive C substitution

substitution is distributive for letters

ie) when we work out for 2x + 5 and 3x -4

we can set = to each other distribute to find x then plug in.

plug in means substitute.

Step-by-step explanation:

transitive is distributive for values for same coefficients in problem solving like Pythagoras a + b = c. but that is not equation checking unless equation replaces it. Answer is substitution for distributive letters.

the answer is a

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
