2 consecutive even numbers add to equal 178. What is the smallest of the 2 numbers?

Diano4ka-milaya [45]

Answer:

The smallest number is 88

Step-by-step explanation:

Let

x ----> the first consecutive even number

x+2 --->the second consecutive even number

we know that

The linear equation that represent this problem is given by

$x+(x+2)=178$

solve for x

$2x=178-2\\2x=176\\x=88$

$x=88\\x+2=88+2=90$

therefore

The smallest number is 88
