Step 1.2.1.1

One to any power is one.

$4 \cdot 1 + y = 2$

$a = 1$

$y = 1$

Step 1.2.1.2

Multiply $4$ by $1$ .

$4 + y = 2$

$a = 1$

$y = 1$

$4 + y = 2$

$a = 1$

$y = 1$

$4 + y = 2$

$a = 1$

$y = 1$

$4 + y = 2$

$a = 1$

$y = 1$

Step 2

Replace all occurrences of $y$ with $1$ in each equation.

Step 2.1

Replace all occurrences of $y$ in $4 + y = 2$ with $1$ .

$4 + 1 = 2$

$a = 1$

$y = 1$

Step 2.2

Simplify the left side.

Step 2.2.1

Simplify $4 + 1$ .

Step 2.2.1.1

Remove parentheses.

$4 + 1 = 2$

$a = 1$

$y = 1$

Step 2.2.1.2

Add $4$ and $1$ .

$5 = 2$

$a = 1$

$y = 1$

$5 = 2$

$a = 1$

$y = 1$

$5 = 2$

$a = 1$

$y = 1$

$5 = 2$

$a = 1$

$y = 1$

Step 3

Since $5 = 2$ is not true, there is no solution.

No solution
