Question

The model represents an equation. What value of x makes the equation true?

Answer 1

An equation is formed of two equal expressions. The value of x that can satisfy this equation is 1.875.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The model represents the equation as given below,

$(6 \times -x)+(6 \times 1) = (2 \times x) + (9 \times -1)\\\\-6x+6=2x-9$

The value of x that can satisfy this equation can be written as,

$-6x+6=2x-9\\\\-6x-2x=-9-6\\\\-8x = -15\\\\8x=15\\\\x = \dfrac{15}{8} = 1.875$

Hence, the value of x that can satisfy this equation is 1.875.
