Question

what is the value of x in the equation represented by the tiles?

Explanation:

Step1: Translate tiles to equation

Left side: $1 + (-x) + (-x) = 1 - 2x$
Right side: $1+1+1+1 + (-x) + (-x) + (-x) = 4 - 3x$
Equation: $1 - 2x = 4 - 3x$

Step2: Isolate x terms

Add $3x$ to both sides:
$1 - 2x + 3x = 4 - 3x + 3x$
$1 + x = 4$

Step3: Solve for x

Subtract 1 from both sides:
$1 + x - 1 = 4 - 1$
$x = 3$

Answer:

$x=3$
