Question

what is x+7=18-2x and please show steps

Answer 1

Simple,

x+7= 18-2x

you want isolate the variable, x, to find what it's value is...

x+7=18-2x
+2x       +2x

Making it..

3x+7=18

still not done...finish isolating the variable...

3x+7=18
     -7   -7

3x=11

$\frac{3x}{3x} = \frac{18}{3}$

=$\frac{11}{3}=3.7 (rounded)$

Thus, your answer is, x=$\frac{11}{3}$.

Answer 2

Simplify both sides of the equation

x+7 = 18-2x

x+7 = 18 + -2x

x+7 -2x+18

Add 2x to both sides

x+7+2x=-2x+18+2x

3x+7=18

Subtract 7 from both sides

3x+7-7=18-7

3x = 11

Divide both sides by 3

3x/3=11/3

x= 11/3

x = 3.67

I hope that's help !
