Question

×+4+×=20 solve for ×

Answer 1

Answer:

$x=8$

Step-by-step explanation:

So we have the equation:

$x+4+x=20$

And we want to solve for x.

First, combine like terms on the left side:

$2x+4=20$

Subtract 4 from both sides:

$(2x+4)-4=(20)-4$

The left side cancels. Subtract on the right:

$2x=16$

Divide both sides by 2. The left side cancels again:

$x=8$

So, the value of x is 8.

And we're done!

Answer 2

Answer:

$\boxed{ \bold{ \huge{\boxed{ \sf{x = 8}}}}}$

Step-by-step explanation:

$\sf{x + 4 + x = 20}$

Collect like terms

$\longrightarrow{ \sf{2x + 4 = 20}}$

Move 4 to right hand side and change it's sign

$\longrightarrow{ \sf{2x = 20 - 4}}$

Subtract 4 from 20

$\longrightarrow{ \sf{2x = 16}}$

Divide both sides by 2

$\longrightarrow{ \sf{ \frac{2x}{2} = \frac{16}{2} }}$

Calculate

$\longrightarrow{ \sf{x = 8}}$
