What number solves the equation x + 7.4 =11.2

Sunny_sXe [5.5K]

The value of x is 3.8

Solution:

Given equation is:

$x + 7.4 = 11.2$

We have to solve the equation for "x"

Move the terms so that you end up with only terms involving x on one side of the sign and all the numbers on the other

Therefore, we get

x + 7.4 = 11.2

When we move 7.4 from left side to right side of equation it becomes -7.4

x = 11.2 - 7.4

Subtract 7.4 from 11.2

x = 3.8

Thus value of x is 3.8
