Answer:
A. divide only on the right side of the equation by 2.
Step-by-step explanation:
I took the test yesterday and I got it hope this helps.
Simplify both sides of the equation.
<span><span>25−n</span>=32
</span><span>Simplify:
</span><span><span><span>−n</span>+25</span>=32
</span>Subtract 25 from both sides.
<span><span><span><span>−n</span>+25</span>−25</span>=<span>32−25
</span></span><span><span>−n</span>=7
</span>Divide both sides by -1.
<span><span><span>−n/</span><span>−1 </span></span>= <span>7/<span>−1
</span></span></span><span>n=<span>−7
</span></span>Ans:
<span>n = <span>−7</span></span><span>

Y = -5x -5
To check, we can insert 0 for y and -1 for x
0 ? (-5X-1) - 5
0 ? 5 - 5
0 = 0
So yes, the equation is correct
Answer:
option B)
x = 2
Step-by-step explanation:
Given in the question the equation:
10x - 3(x- 6) = x + 30
Simplify the left side
10x - 3(x - 6) = x + 30
10x - 3x + 18 = x + 30
rearrange the terms and containing x to the left side of the equation and add accordingly
x(10 - 3 - 1) = (30 - 18)
x(10 - 4) = (12)
x(6) = 12
6x = 12
Divide each term by 6 and simplify
x = 12/6
x = 2
