Answer:
x=32/7
Step-by-step explanation:
7x-2(1)=30 Plug in 1 as y and simplify.
7x-2=30 Add 2 on both sides of the equation.
<u>+2 +2</u>
7x=32 Divide both sides of the equation by 7.
<u>/7 /7</u>
x=32/7
Hope this helps...have an amazing day (。・∀・)ノ゙
Answer: -4
Step-by-step explanation:reverse the steps
3(x-7)= -9
3(x-7)/3= -9/3
x-7= -3
x= -3+7
x= -4
For the answer to the question above, that should be easy.
Just replace the z into 4.
(2z+1) will be (2(4)+1)
Thus, (8+1)
Then the answer would be 9
Same as the second one
given: 3z-6
Just change it into z into 4
so 3(4)-6
(12-6)
So the answer would be 6
Then the final answer for the two equations are
4 and 6
if you would multiply it. you'll get 54
I hope my answer helped you.
Answer:
11>9
Step-by-step explanation:
So you can begin by plugging x=1 into the equation
3(1)+8>9
3*1=3
3+8=11
11>9
