Given: 4x - 7 = 2x + 9 prove: x = 9 what is the missing reason? 1. 4x - 7 = 2x + 9 1. given 2. 2x - 7 = 9 2. 3. 2x = 18 3. addition property of equality 4. x = 9 4. division property of equality a) multiplication property of equality b) subtraction property of equality c) transitive property of equality d) substitution property of equality

B)Subtraction property of equality

Step-by-step explanation:

4x - 7 = 2x + 9

Subtract 2x from each side using the subtraction property  of equality

4x -2x  - 7 = 2x-2x + 9

2x -7 = 9

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
