The distributive property is also known as the distributive law of multiplication over addition and subtraction.
-220 = -5(5x+4)
Step1:
Open the parentheses by the distribution property
-220 = -25x - 20
Step2:
Switch 25x and 220, and multiply each side by -1
-25x = -220 + 20
Step3:
Subtract:
-25x = -200
Step4:
Divide -200 by -25
Answer: x = 8
