What is 0.40x+10=45 in math

x = 87.5

Explanation:

0.4x + 10 = 45

Subtract 10 from both sides

0.4x + 10 - 10 = 45 - 10

0.4x = 35

Divide both sides by 0.4

0.4x / 0.4 = 35 / 0.4

x = 87.5

x=87.5

Step-by-step explanation:

I'm pretty sure they ask you to solve for x. So you need to make x as alone on one side. To do that, I will move + 10 to other side by subtracting by 10 for both sides. 0.40x=35. Now, we need to solve for x. So x must be 1. To do that, I will divide 0.40 for both sides which gives you the answer. x=87.5
