Answer:
Step-by-step explanation:
(x-7)2=36
Can also be written the other way round with the 2 infront
2(x-7)=36
You can divide both sides by 2
2(x-7)/2=36/2
x-7=18
To solve for x add 7 to both sides this will get x on its own
x-7+7=18+7
x=25
To check if our answer is correct simply substitute
x=25 into the original equation
(25-7)*2=36
True as Left side=Right side
