Step-by-step explanation:
Let's solve your equation step-by-step.
25x+(35)(8)+(15)(2)=385
Step 1: Simplify both sides of the equation.
25x+(35)(8)+(15)(2)=385
25x+280+30=385
(25x)+(280+30)=385(Combine Like Terms)
25x+310=385
25x+310=385
Step 2: Subtract 310 from both sides.
25x+310−310=385−310
25x=75
Step 3: Divide both sides by 25.
25x
25
=
