Question

1. 2 + x = 3\
2. 1.3 + x = 5

Explanation:

Step1: Isolate x for first equation

Subtract 2 from both sides:
$2 + x - 2 = 3 - 2$

Step2: Solve first equation

Simplify to find x:
$x = 3 - 2 = 1$

Step3: Isolate x for second equation

Subtract 1.3 from both sides:
$1.3 + x - 1.3 = 5 - 1.3$

Step4: Solve second equation

Simplify to find x:
$x = 5 - 1.3 = 3.7$

Answer:

1. $x=1$
2. $x=3.7$
