<u>Step by Step Explanation:</u>
16. x - 4 = 4
Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides:
x - 4 (+4) = 4 (+4)
x = 4 + 4
x = 8
17. a/4 = 4
Isolate the variable (a). Note the equal sign, what you do to one side, you do to the other. Multiply 4 to both sides:
(a/4)(4) = (4)(4)
a = (4)(4)
a = 16
18. y * 20 = 30
Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. Divide 20 from both sides.
(y *20)/20 = (30)/20
y = 30/20
y = 3/2 or 1.5
19. x/5 = 20
Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Multiply 5 to both sides
(x/5)(5) = (20)(5)
x = (20)(5)
x = 100

Answer:
4+3(7+4*2) - 100 = -51
Step-by-step explanation:
4+3(7+4*2) - 100
= 4 + 3 (15) - 100
= 4 + 45 - 100
= -51
