Answer: X = 1

Step-by-step explanation

Step 1: First distribute the 5. 5*x = 5x 5*2=10

Step 2: So now you have 5x+10-7=3x+5

Then you want to combine like terms (CLT)

10-7= 3

5x+3=3x+5

Step 3: Now you want to have opposite integers

5x+3=3x+5

-3 -3

5x=3x+2

Step 4: Like the last step but with the numbers that have variables

5x=3x+2

-3x -3x

2x=2

Step 5: Now you want to divide the variable with the whole number

2x=2

x = 1

Answer:

x = 1

Explanation:

Solve using inverse operations

5 ( x + 2 ) - 7 = 3x + 5

first distribute the 5

5x + 10 - 7 = 3x + 5

simplify the expression

5x + 3 = 3x + 5

Inverse operations, then simplify

5x + 3 = 3x + 5

-3 -3

5x = 3x + 5 - 3

5x = 3x + 2

-3x -3x

2x = 2

/2 /2

x = 1
