Answer:
B) -4
C) -5
Step-by-step explanation:
B)
So we have:
[tex]3(2x+4)=-12[/tex]
First, divide both sides by 3. The left side cancels:
[tex]2x+4=-4[/tex]
Subtract 4 from both sides. The left side cancels:
[tex]2x=-8[/tex]
Divide both sides by 2. The left side cancels:
[tex]x=-4[/tex]
C)
We have:
[tex]4(5-2x)=60[/tex]
Divide both sides by 4, the left side cancels:
[tex]5-2x=15[/tex]
Subtract 5 from both sides:
[tex]-2x=10[/tex]
Divide both sides by -2:
[tex]x=-5[/tex]
And we're done!
