Solve the equation 3(x + 1) − 2 = x + 5. Question 12 options: x = 2 x = 3 x = 4 x = 3.5

svlad2 [7]

x = 2

Step-by-step explanation:

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

3x + 3 - 2 = x + 5

3x + 1 = x + 5

3x - x = 5 - 1

2x = 4

x = 4 / 2

x = 2

The expression on the left side of an equation is shown below.

nlexa [21]

Expression that can be written in the box on the other side of the equation will be x

Step-by-step explanation:

The left side of equation is: $-4(x-2)+5x$

Simplifying the equation we get:

$-4(x-2)+5x\\=-4x+8+5x\\=-4x+5x+8\\=x+8$

An equation has no solution when, we cannot find the value of x.

So, The order side of equation can be x

i.e,

$-4(x-2)+5x=x\\x+8=x\\x-x=-8\\0\neq 8$

So, expression that can be written in the box on the other side of the equation will be x
