Step-by-step explanation:
7/10-1/2=←Write the equation
7/10-5/10=←Make it into a common denominator and subtract
2/10=←Simply if possible
1/5←This is the simplest form
Answer:
x=−8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(x+5)=21
(−7)(x)+(−7)(5)=21(Distribute)
−7x+−35=21
−7x−35=21
Step 2: Add 35 to both sides.
−7x−35+35=21+35
−7x=56
Step 3: Divide both sides by -7.
−7x/−7 = 56/−7
x=−8
