Answer: A) x = 2

Step-by-Step Explanation:

9(x + 1) = 25 + x
9 * x + 9 * 1 = 25 + x
9x + 9 = 25 + x (Shift +x to LHS)
9x - x + 9 = 25 (Shift +9 to RHS)
9x - x = 25 - 9
8x = 25 - 9
8x = 16 (Shift *8 to RHS)
x = 16/8
=> x = 2

Therefore, x = 2

Answer: 0=0

Step-by-step explanation:

First you want to solve for x

2x+y=−4

Step 1: Add -y to both sides.

2x + y + −y =−4+ −y

2x=−y−4

Step 2: Divide both sides by 2.

2x/2= -y-4/2

x=-1/2y-2

Then you want to plug in your answer for x into the equation so:

2(-1/2y-2)+y=-4

Step 1: Simplify both sides of the equation.

2(-1/2y-2)+y=-4

(2)( −1/ 2 y)+(2)(−2)+y(Distribute)

−y+−4+y=−4

(−y+y)+(−4)=−4(Combine Like Terms)

−4=−4

Step 2: Add 4 to both sides.

−4+4=−4+4

0=0.

Sorry if this wasn't the answer your looking for. If you need more help I suggest using Ma.th.Pa.pa calculator but with out the periods. Hope you have a good day :)
