Answer:
For question 7
b) x = 4
c) x = -6
d) x= -14
e) x = 14
f) x = 4
Step-by-step explanation:
b)
[tex]4x - 16 = 0 \\ 4x = 16 \\ x = 4[/tex]
add 16
divide by 4
c)
[tex]2.5x = - 15 \\ x = - 6[/tex]
divide by 2.5
d)
[tex] \frac{1}{2} x = - 7 \\ x = - 14[/tex]
divide by 1/2 (multiply by 2)
e)
[tex] - \frac{1}{4} x = - 3.5 \\ x = 14[/tex]
