Help .. 3(x+2)=5x+1-2x+5

Hunter-Best [27]

Answer:

All real numbers are solutions

Step-by-step explanation:

Let's solve your equation step-by-step

3(x+2)=5x+1−2x+5

Step 1: Simplify both sides of the equation

3(x+2)=5x+1−2x+5

(3)(x)+(3)(2)=5x+1+−2x+5(Distribute)

3x+6=5x+1+−2x+5

3x+6=(5x+−2x)+(1+5)(Combine Like Terms)

3x+6=3x+6

Step 2: Subtract 3x from both sides

3x+6−3x=3x+6−3x

6=6

Step 3: Subtract 6 from both sides

6−6=6−6

quester [9]

Answer:

The answer is:

$\frac{2a}{2b} = 5$

Step-by-step explanation:

Substitute the values of a and b into the equation

$a = 10&b = 2 \\ \\ \frac{2a}{2b} = 5 \\ \\so \frac{2(10)}{2(2)} = 5$

$\frac{20}{4} = 5 \\ \\ 5 = 5$
